What’s (3b-5c)(2x+5y) squared

Mathematics

Answer: In your problem, you said that they are squared. However, it is not written as squared. We just have to multiply them.

We can use the FOIL method.

(3b - 5c)(3x + 5y)

6bx + 15by - 10cx - 25cy

There are no like terms, so that expression is our final answer.

The triangles are similar. If QR = 9, QP = 6, and TU = 19, find TS. Round to the nearest tenth.

Answer=12.6

QR=9
QP=6
TU=19
TS=?

The triangles are similar, so the following equation can be made

   9         6
____=____
  19        x        

Cross multiply
9x=114
divide both sides by 9
x=12.6 (with the 6 repeating) or 12 2/3

TS=12.6
