If DG = 10, what is the value of x?

x = 8

Step-by-step explanation:

DG = 10

(x + 1) + (2x - 15) = DG

so;

x + 1 + 2x - 15 = 10

3x - 14 = 10

3x = 10 + 14

3x = 24

x = 24/3

x = 8

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
