use the zero product property to find the solutions to the equation (x+2)(x+3)=12
Answer:
x=-6, x=1
Step-by-step explanation:
The zero product property
It states that if a.b=0, then it must be satisfied that a=0 or b=0. It's commonly used to solve equations where one of the sides is 0.
The given equation is:
(x+2)(x+3)=12
Since neither side is 0, we operate the expression:
x^2+3x+2x+6=12
Moving 12 to the left side and simplifying:
x^2+3x+2x+6-12=0
x^2+5x-6=0
Factoring:
(x+6)(x-1)=0
Now, since there is zero on the right side, we apply the property to solve:
x+6=0, or x-1=0
The two solutions come directly:
x=-6, x=1
You can buy 5 cans for green beans at the Village Market for $3.70. You can buy 10 of the same cans of beans at Sam's Club for $6.90. Which place is the better buy?
Answer:
1 can of green beans at Village Market is $0.74. At Sam's Club, one can of green beans is $0.69. Therefore, Sam's Club is the better buy, by being cheaper than Village Market's by $0.05.
Step-by-step explanation:
Nikki used the calculations shown to determine whether a carton of 12 eggs or a carton of 18 eggs was the better buy. A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39. Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg The 12-egg carton has the lower unit cost, so it is the better buy. What was her first error?
Given :
A carton of 12 eggs or a carton of 18 eggs was the better buy. A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39. Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg The 12-egg carton has the lower unit cost, so it is the better buy.
To Find :
What was her first error.
Solution :
Her first error is to find Unit price of egg in each carton.
To find, unit price we should divide total amount by number of units :
Unit price for carton of 12 eggs, $ (2.39)/12 = $0.199 .
Hence, this is the required solution.
Answer:
She is right, however her explanation is wrong.
In order to find the unit price, you need to divide the amount by the cost.
You will then see that 12 divided by 2.39 < 18 divided by 3.39.
The smaller unit price is obviously the better buy.

If f(x)= 2x-5, then what is the value of f(2) + f(5)
Answer:
4
Step-by-step explanation:
replace x with 2 then you get -1
Next step replace x with 5 then u get 5
Add 5 and -1. You get four.
The value of f(2) + f(5) in f(x) = 2x - 5 is 4.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, f(x)= 2x-5, therefore f(2) + f(5) can be obtained if we replace x with numerical values 2 and 5 in f(x) which is,
f(2) + f(5) = 2(2) - 5 + 2(5) - 5.
f(2) + f(5) = 4 - 5 + 10 - 5.
f(2) + f(5) = 4

Janet hiked 3/8 mile in 1/4 hour. How fast did she hike, per hour?
Answer: answer is A
A:3/32
B:2/3
C: 1 1/2
D:4
She hike 1.5 miles per hour.A common unit of measurement is the mile (mi).
How to fast she hike per hour?1.609344 kilometers are exactly one unit of length. mile, any of several different measures of distance, such as the statute mile, which has a length of 5,280 feet, is also equivalent to 1,760 yards (1.609 km). It derives from the mile passus, or "thousand paces," of the Romans, which was equivalent to 5,000 Roman feet.
A common unit of measurement is the mile (mi). It is typically used to express the distance between cities, the length of rivers, and the distance between roadways. The letter "mi" stands for the unit mile in writing. Therefore, a marathon race would be roughly 26.3 miles or 26.3 mi in length.
Given ,
1/4hrs=15mins
15mins=3/8miles
60mins=more
60/15 × 3/8

Use the figure to find the measures of the numbered angles.
Answer:
95 degrees is the measure of 3 just like the other angle because they equal each other the angle of 4 you would find out by subtracting 180-95=85. so the measure of 3 is 95 and the measure of 4 is 85

Hayden likes building radio-control sailboats with his dad.One of the sails shaped like a triangle has side lengths measuring 6 inches 8 inches and 10 inches. To log her activity Hayden creates and collects drawings of all the boats she and her father built together. Using the scale factor of 1/4 creat a scale drawing of the sail.
Answer:
1.5 inches ; 2 inches ; 2.5 inches
Step-by-step explanation:
Given that the original measurement of the triangular sail is :
6 inches, 8 inches and 10 inches
Scale factor = 1/4
Hence, scaled diagram of the triangular sail :
1/4 * (6 inches, 8 inches, 10 inches)
1/4 * 6 = 1.5 inches
1/4 * 8 = 2 inches
1/4 * 10 = 2.5 inches

Using the figure below, find the measure of z ( just enter in the number for your answer don’t worry about the degree symbol or saying “ degrees” after the number
Answer:
z = 29°
Step-by-step explanation:
We know that the 3 angles in a triangle always add up to 180°. So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).
angle A + angle B + angle C = 180°
59° + 92° + z = 180°
151° + z = 180°
Subtract 151° from both sides of the equation
z = 180° -151°
z = 29°

Souvenir hats, T-shirts, and jackets are sold at a rock concert. Three hats, two T-shirts, and one jacket cost $40. Two hats, two T-shirts, and two jackets cost $60. One hat and three T-shirts cost $10. Find the prices of the individual items. (you have to use substitution and/or elimination method, NO matrix or Graph.)
Answer:
j = 24
t = 2
h = 4
Step-by-step explanation:
Three hats, two T-shirts, and one jacket cost $40.
3h + 2t + j = 40
Two hats, two T-shirts, and two jackets cost $60.
2h + 2t + 2j = 60
One hat and three T-shirts cost $10.
h + 3t = 10
3h + 2t + j = 40 (1)
2h + 2t + 2j = 60 (2)
h + 3t = 10. (3)
From (3)
h = 10 - 3t
Substitute into (1) and (2)
3(10 - 3t) + 2t + j = 40 (1)
2(10 - 3t) + 2t + 2j = 60 (2)
30 - 9t + 2t + j = 40
20 - 6t + 2t + 2j = 60
- 7t + j = 40 - 30
-4t + 2j = 60 - 20
-7t + j = 10 (1a)
-4t + 2j = 40 (1b)
Multiply (1a) by 2
-14t + 2j = 20
-4t + 2j = 40
Subtract to eliminate j
-4t - (-14t) = 40 - 20
-4t + 14t = 20
10t = 20
t = 20/10
t = 2
Substitute t = 2 into
h = 10 - 3t
h = 10 - 3(2)
= 10 - 6
= 4
h = 4
Substitute t = 2 and h = 4 into
3h + 2t + j = 40
3(4) + 2(2) + j = 40
12 + 4 + j = 40
16 + j = 40
j = 40 - 16
= 24
j = 24

At a candy store, Jeremiah bought 1 pound of jelly beans for $9. Meanwhile, Emma bought 4
pounds of jelly beans and 6 pounds of gummy worms for $60. How much does the candy
cost?
Plz help ASAP
Answer:
I think the candy cost 51 dollars
Jellybeans: 36$
Gummy worms: 15$
36 + 15 = 51
Step-by-step explanation:
Since jeremiah bought 1 pound for 9 dollar you can minus 9 from the equation which is 51 and since each pound of jelly beans were 9 dollars 9 x 4 = 36 and 51 - 36 is 15 so the cost of the gummy worms are 15 so
either 51 or 36 and 15
