(50-(x*50))+(40-(y*40))+20= discounted with 2 coupons
110-(z*110)= the price with the total coupon.
I believe these are the correct answers
Area: 20 x 30 so 600
perimeter: 20 + 20 + 30 + 30 = 100

Answer:
d
Step-by-step explanation:
The triangles are similar, thus the ratios of corresponding sides are equal, that is
=
=
( cross- multiply )
5(2x + 1) = 8(x + 4) ← distribute parenthesis on both sides )
10x + 5 = 8x + 32 ( subtract 8x from both sides )
2x + 5 = 32 ( subtract 5 from both sides )
2x = 27 ( divide both sides by 2 )
x = 13.5 → d
