Which equation results from taking the square root of both sides of (x 9)2 = 25? x 3 = ±5 x 3 = ±25 x 9 = ±5 x 9 = ±25.
The equation which is results from taking the square root of both sides of the provided equation is,
[tex](x+9)=\pm5\\[/tex]
What is the square root?A square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.
Let a number is a. Then this number in the form of square root can be written as,
[tex]a=\sqrt{a}\times \sqrt{a}[/tex]
The given algebraic equation in the problem is,
[tex](x+ 9)^2 = 25[/tex]
Take the square root, in both sides,
[tex]\sqrt{(x+ 9)^2} = \sqrt{25}\\\sqrt{(x+ 9)^2} = \sqrt{5^2}[/tex]
Cancel out the square root with the square of the number as,
[tex](x+9)=\pm5\\[/tex]
Hence, the equation which is results from taking the square root of both sides of the provided equation is,

a wood worker wants to cut a board that is 8,225 feet long into 5 equal-length pieces. how long will each of the boards be
Solving
Before starting to solve the question we can easily identify that we need to divide the total number by the amount of equal pieces.
The reason we are going to divide is because when you divide a number you are distributing it into equal groups.
8,225 ÷ 5 = 1645
Answer
Meaning each of the boards will be 1645 feet in length

© Krutika was thinking of a number. Krutika adds 10, then divides by 5 to get an answer of -14.
What was the original number?
0
Answer:
-16
Step-by-step explanation:
10 Divided by 5=2
-16 + 2 = -14
Answer:
The answer should be -80
Step-by-step explanation:
When you do the problem backwards you can get the answer. So, if you take -14, then multiply by 5, you get -70, then if you subtract 10, you get -80

What is the surface area of the triangular prism?
What is the volume of the triangular prism?
PLEASE HELP
Surface Area:
A triangular prism is made up of 3 rectangles and 2 triangles.
Area of a rectangle = base x height
Area of a triangle = 1/2 x base x height
Rectangle: 5.6 x 2.7 = 15.12
All 3 rectangles: 15.12 x 3 = 45.36
Triangle: 1/2 x 2.7 x 2.3 = 3.105
Both triangles: 3.105 x 2 = 6.21
Surface Area: 45.36 + 6.21 = 51.57 mm^2
Volume:
Volume of a triangular prism = base area x height
Triangle area = 3.105
Height = 5.6

Bobby's cat runs at x mph. Bobby's dog runs twice as fast as his cat.
Suppose Bobby's cat and dog were 6 miles apart after 30 minutes. Write an equation to
Answer:
3x/2 =6
Step-by-step explanation:
The distance between the dog and cat is 6 miles. Then the equation is 30x = 6 or x = 0.2.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
[tex]\rm Speed = \dfrac{Distance}{ Time }[/tex]
Bobby's cat runs at x mph. Bobby's dog runs twice as fast as his cat.
The speed of a cat is x. Then the speed of the dog is 2x.
The distance traveled by the cat in 30 minutes will be
[tex]\rm D_c = 30 \times x\\\\D_c = 30 \ x[/tex]
The distance traveled by the dog in 30 minutes will be
[tex]\rm D_d = 30 \times 2x\\\\D_d = 60 \ x[/tex]
Suppose Bobby's cat and dog were 6 miles apart after 30 minutes.
[tex]\rm D_d - D_c \ \ = 6\\\\60x - 30x = 6\\\\30x = 6[/tex]

At a concert , tickets cost either $40 or $60. 700 tickets were sold at a cost of $33600, find how many $40 tickets were sold
Answer:
420 $40 tickets.
Step-by-step explanation:
Here is the explanation.
1. As 700 tickets cost a total of $33600, the average cost of each ticket is $48.
2. As there are 700 total tickets with each costing $40 or $60, we can use the total cost ($33600) to define the amount of each ticket.
3. If there were to be 420 $40 tickets, there will be 280 $60 tickets.
4. This means that the cost of each price of tickets ($40 and $60) will be distributed evenly among the total price, each costing $16800.
5. 420 x 40=16800 280x60=16800
6. There are 420 $40 tickets sold at the concert.

Answer:
156 children145 adultsStep-by-step explanation:
Let number of adults be a and children be c
Then we have equations
a + c = 3014a + 1.5c = 814From the first equation we get a = 301 - c, we substitute a in the second equation:
4(301 -c) + 1.5c = 8141204 - 4c + 1.5c = 8142.5c = 1204 - 8142.5c = 390c = 390/2.5c = 156Then finding the value of a:
