P = 2l + 2w    |subtract 2w from both sides

2l = P - 2w    |divide both sides by 2

l = (P - 2w)/2

B is the midpoint of segment AC trying to find AB using the definition of midpoint.
Kipish [7]

Answer:

12

Step-by-step explanation:

A midpoint of a line means that each segment connecting from the midpoint to an end is equal. For this problem, this means that AB = BC, as B is the midpoint, and A and B are the ends. Therefore, we can say that:

AB = BC

2x + 6 = 5x - 3

add 3 to both sides

2x + 9 = 5x

subtract 2x from both sides

9 = 3x

divide both sides by 3

3 = x

Plugging 3=x into AB, this means that 2(3) + 6 = AB = 12

The answer to A. is 108cm or 1.08m

First convert 2m to cm:
2m x 100 = 200 cm
Next convert 6m to cm:
6m x 100 = 600 cm
Divide the height of the person by his/her shadow:
200cm ÷ 600cm = <span>0.33333333333 = .3</span>
Multiply 360cm by .3:
360cm x .3 = 108cm
108cm ÷ 100 = 1.08m

The answer to B. is 6.8 cm.

The scale seems a bit small... are you sure you don't mean 0.8 m?
a = length of actual car.
8.5 x 0.8 = 1 x a
6.8 = 1 x a
6.8 ÷ 1 = a
6.8 = a

If you did mean 0.8 m... the answer is 680 cm or 6.8 m.

a = length of actual car.
0.8m x 100 = 80cm
8.5 x 80 = 1 x a
680 = 1 x a
680 ÷ 1 = a
680 = a
680 ÷ 100 = 6.8

Answer:

5

Step-by-step explanation:

When squaring the number 5 (i.e 5^2 ) the answer is 25. 5^{2} is the same thing as 5 times 5. Basically with the square root, you are going backwards, so you are therefore finding the base of it all.
