rick believes the two expressions 4(3a-3) +2a and 14a-3 are equivalent. is he correct? explain why or why not?

Answers

Answer 1
12a-12+2a = 14a-3
14a-12 = 14a-3

So he’s not correct.
Answer 2

Answer:

no

Step-by-step explanation:

4(3a-3)+2a when you expand youget

((4x3a)-(4x3)) + 2a = 12a - 12 + 2a then we collect the like term first 12a + 2a - 12

14a -12

therefore 14a - 12 is not equal to 14a- 3

find missing factor 7^-5 = blank × 7^6

Answers

Answer:

7^-11

Step-by-step explanation:

Given the expression 7^-5 = blank × 7^6

Let the blank be x

7^-5 = x × 7^6

x = 7^-5/7^6

According to law of indices a^b/a^c = a^b-c

x = 7^(-5-6)

x = 7^-11

Hence the missing factor is 7^-11

Heather finished the 12-kilometer race in 2 hours. If Heather kept her pace constant, what was her rate? A. 24 km/hr. B. 14 km/hr. C. 10 km/hr. D. 6 km/hr.

Answers

Answer: D, 6km/hr.

Step-by-step explanation:

Heather can finish a 12-kilometer race in 2 hours, and now we have to find how many kilometers she can ride/run at in 1 hour.

How many hours can Heather run in 1 hour? To solve that, we can use the equation 12 ÷ 2.

12 ÷ 2 = 6.

Therefore, if Heather keeps her pace constant, then her rate will be 6km/hr, or D.

A block of ice is in the shape of a rectangular prism. The ice block has a volume of 9,600 cubic inches. After being in a warm area, the size of the block is now 18 inches by 12 inches by 20 inches.

What is the difference between the volume of the ice block before and after it melted?

Answers

Answer:

5280 cubic inches

Step-by-step explanation:

V= l * w * h

V= 18 * 12 * 20

V= 4320 cubic inches

Then do the first measurement subtracted by the second one because it wants to know the difference.

9600 - 4320 = 5280 cubic inches

Answers

x2=36

We move all terms to the left:

x2-(36)=0

We add all the numbers together, and all the variables

x^2-36=0

a = 1; b = 0; c = -36;

Δ = b2-4ac

Δ = 02-4·1·(-36)

Δ = 144

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

x1=−b−Δ√2ax2=−b+Δ√2a

Δ‾‾√=144‾‾‾‾√=12

x1=−b−Δ√2a=−(0)−122∗1=−122=−6

Answer:

  x = -6 or +6

Step-by-step explanation:

You know from your multiplication tables that 6×6 = 36, so one answer is ...

  x = 6

You also know that the product of two negative numbers is positive, so another answer is ...

  x = -6

__

Check

  x² = 6² = 6×6 = 36

  x² = (-6)² = (-6)×(-6) = 36

_____

Alternate approach

If you like, you can rewrite the equation as ...

  x² -36 = 0

This can be factored to ...

  (x -6)(x +6) = 0

The zero product rule tells you this product will only be zero if one or the other factors is zero.

  x -6 = 0   ⇒   x = 6

  x +6 = 0   ⇒   x = -6

The two solutions are x = ±6.

Answer:

76 feet (Just put 76 in the answer box)

Step-by-step explanation:

Knowing the perimeter of a rectangle is 2l + 2w, multiply 2 by 3.5. Then multiply 2 by 4.5, and add them together.

2(3.5) + 2(4.5)

The two products would be 7 and 9 respectively.

7 + 9 = 16 feet of fencing for 1 rabbit pen.

We have 2 pens, so multiply 16 by 2.

The rabbit pens need 32 feet of fencing.

(Alternatively you could have done 2(2(3.5 + 4.5)).

2(2(8))

2(16)

32 ft of fencing (rabbit pens))

Now, add 12 and 10. Then multiply that by 2.

2(12 + 10)

2(22)

The garden needs 44 feet of fencing.

Now add 32 and 44 to get the total amount of fencing needed.

32 + 44

The rabbit pens and the garden need 76 feet of fencing. (Just put 76 in the answer box as the unit (feet) is already given.)

Answers

Sorry need points right now

4n - 8 > n + 17

n > 8.33

This means n is greater than 8.33.

We can have 9, 10, 11, 12, 13, ,,, and so on.

The least value is 9.

The least value of the number of sheep is 9.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

Rashid:

Number of sheep owned = n

Bought 17 sheep = n + 17

Eifion:

Number of sheep owned = 4n

Sells 8 sheep = 4n - 8

Eifion still has more sheep than Rashid.

This means,

4n - 8 > n + 17 ______(1)

Solving for n in (1).

4n - 8 > n + 17

Subtract n on both sides.

4n - 8 - n > n + 17 - n

3n - 8 > 17

Add 8 on both sides.

3n - 8 + 8 > 17 + 8

3n > 25

Divide 3 on both sides,

n > 25/3

n > 8.33

This means n is greater than 8.33.

We can have 9, 10, 11, 12, 13, ,,, and so on.

The least value is 9.

Thus,

The least value of the number of sheep is 9.

Use the slope formula given in the question to solve for the slope. The [tex]m[/tex] is the variable representing the slope. The [tex]x_1[/tex] and [tex]y_1[/tex] values are x and y values of one point. The [tex]x_2[/tex] and [tex]y_2[/tex]  are x and y values of another point.
