1. Combine like terms (simplify)
4x – 3 + 2 – 2x + 2(3x - 6) =

2. Combine like terms (Simplify
9(r –s) + 5(2r – 2s) =

3. Combine like terms (Simplify)
4(8m – 7n) + 6(3n – 4m) =

4. Put back into factored form:
144t - 36

5. Put back into factored form:
8x-12

1. 8x - 13

2. 19r - 19s

3. 8m - 10

4. 36(4t - 1)

5. 4(2x - 3)

Step-by-step explanation:

For the first three it’s pretty basic, just follow PEMDAS

for the last two, just find the largest number that divides into both of them and take it out

7

step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
