Answer:
3x^2 + 2x - 3y - 10
Step-by-step explanation:
7y + 2x - 10y +3x^2 - 10x
I like to put it in order starting with exponents like this
3x^2 + 2x - 10x + 7y - 10y
then combine like terms
3x^2 - 8x - 3y
that is as simplified as it gets.
Answer:

Answer:
XQ = 12
Step-by-step explanation:
In this question it asks for XQ instead of x, but you need to find x first.
1. Find x.
XQ is half of MQ so this statement is true: 3x - 3 = 2(2x - 6)
Solve for x.
3x - 3 = 2(2x - 6)
Distribute 2.
3x - 3 = 4x - 12
Isolate x.
3x = 4x - 9
-x = -9
Divide -1 out.
x = 9
Now solve for XQ, which the equation is given.
XQ = 2(9) - 6
XQ = 18 - 6
XQ = 12
Answer: 7
Step-by-step explanation:
Since squares have the same side lengths
then you need to find a number that multiplies twice that equals 49
7*7 = 49
