Answer:
x = 13
Step-by-step explanation:
ΔRST≈ΔYSZ
therefore:
RT/ST = YZ/SZ
(3x-7)/40 = (2x+2)/35
cross-multiply:
40(2x+2) = 35(3x-7)
80x+80 = 105x-245
80 = 25x-245
325 = 25x
325/25 = x
x = 13
Answer:
<u>Area= 10 </u>

Answer:
(4+5)3-8 = 19
Step-by-step explanation:
1) You know that the parenthesis are going to go around 3-8 or 4+5 because that is the only way multiplication is involved. If you put them anywhere else it doesn't change the answer.
2) Try solving the problems (use PEMDAS)
(4+5)3-8 = 9*3-8 = 27-8 = 19
4+5(3-8) = 4+5(-5) = 4-25 = -21
