If triangle CDE is dilated by a scale factor of 1/5 with a center of dilation at vertex E, what is the area of triangle C'D'E'?

timurjin [86]

The correct answer would be Choice B: 4 square units.

When the scale factor is 1/5, that means the lengths of the sides are 1/5 of the original size. So instead of having a base of 20 and height of 10, the new triangle has a base of 4 and a height of 2.

The area of the triangle is: (4 x 2) / 2 = 4

1.5c - 6 = 7.5 i need help with this problem and i have no one to help me

Lostsunrise [7]

Answer:

c=9

Step-by-step explanation:

Let's solve your equation step by step:

add 6 on both sides
divide 1.5 from the product of 6 and 7.5 (aka 13.5)
you will get C
put 9 in for C.

<h2> $1.5c-6=7.5$ </h2>

1. $1.5c-6+6=7.5+6$

1.5 $1.5c=13.5$

2. $\frac{1.5c}{1.5c}=\frac{13.5}{1.5c}$

3. C=9

1.5(9)-6=7.5

13.5-6=7.5
