Point L is on line segment KM. Given LM = 3x + 3,
iris [78.8K]

Answer:

KM = 4

Step-by-step explanation:

LM = 3x + 3

KM = 5x + 4

KL = 5x + 1

KL + LM = KM (segment addition postulate)

(5x + 1) + (3x + 3) = 5x + 4 (substitution)

Solve for x

5x + 1 + 3x + 3 = 5x + 4

Combine like terms

8x + 4 = 5x + 4

8x + 4 - 4 = 5x + 4 - 4

8x = 5x + 0

8x - 5x = 0

3x = 0

x = 0

KM = 5x + 4

Plug in the value of x

KM = 5(0) + 4

KM = 0 + 4 = 4

Type the correct answer in the box
ivolga24 [154]

Answer:

w=V/(lh)

Step-by-step explanation:

Let

l------> the length of the base of the prism

w------> the width of the base of the prism

h------> the height of the prism

we know that

The volume of the prism is equal to

V=lwh

Solve for w

That means-------> isolate the variable w

so

Divide both sides by (lh)

V/(lh)=lwh/(lh)

Simplify

w=V/(lh)
