8 0

Answer:

a = 3

Step-by-step explanation:

The triangles are similar, so the ratio of short side to long side is the same for each:

(a +5)/12 = 12/18

a +5 = 12(12/18) = 8 . . . . . multiply by 12

a = 3 . . . . . . subtract 5

loris [4]

Answer:

A) 5 and B) 5

Step-by-step explanation:

A) 5x-12=13

+12 +12 (add 12 to the 13)

5x=25

(then divide 25 by 5 which is 5 so the answer is 5)

B) 8(x+3)=64 (first use distributive property)

8x+24=64

-24 -24 (then subtract 24 to 64 which is 40)

8x=40

(then divide 40 by 8 which is 5 so that is it!)

I believe this is correct, I hope this helps :D
