Answer:
M = 7x² +21
Step-by-step explanation:
Subtract the unwanted terms on the left from both sides.
(-7x² +6x -16) + M = 6x +5
M = 6x +5 -(-7x² +6x -16)
M = 7x² +21 . . . . simplify
6x + 9y =36 is the Answer
Answer:

Step-by-step explanation:
Recall that
. Using this, we can simplify and combine the two terms:
. Therefore, the terms may be combined.
Its the number that multiplies x
6.25
2(3x +x)=30
8x = 30
x =3.75 = width
3x = 11.25 = length
