Question

if AD=2x+3 and CD=x+10, what is the value of x?

Answer 1

I think something's missing from this question. What do AD and CD represent?

Answer 2

they are congruent

Answer 3

answers (a)9 (b)11 (c)7 (d)15

Answer 4

AD = CD
2x + 3 = AD
x + 10 = CD

Therefore
2x + 3 = x + 10

Solve for x.

Answer 5

OK, so if AD=CD then sent the two statements equal
\[2x+3=x+10\] and solve for x

Answer 6

Move the 1x to the other side, and the 3 to the other side and the answer presents itself.

Answer 7

is it 7?

Answer 8

Very good.

Answer 9

Yes
