5(5x-10)=15
5x-10=3
5x=10+3
5x=13
Divide both sides by 5-5 and 5 cancel out to leave you with x 13/5 =2.6
X=2.6
Answer:
The answer A
Step-by-step explanation:
B: You need a side that is longer than 2 equal sides. B is incorrect.
A: Try
9^2 + 12^2 = 15^2 if that works, A will work.
81 + 144 = 225
This works. I used these numbers because they were easier to see.
0.9^2 + 1.2^2 = 1.5^2
0.81 + 1.44 = 2.25
2.25 = 2.25
That is the answer A
But we have to check the other two.
C:
0.9^2 = 0.81
1.2^2 = 1.44
1.8^2 = 3.24 This won't work. 3.24 is just too big.
D:
0.9^2 = 0.81
0.6^2 = 0.36
1.5^2 = 2.25 It's too far away.
