8y+22=y-12

First way:
—> subtract 2y and 22 from both sides to get 6y= -34
—> divide both sides to get 3y= -17
—> divide both sides by 3 to get y= -(17/3)

Second way:
—> add 12 to both sides and -8y from both sides to get -6y= 34
—> divide both sides by 2 to get -3y= 17
—> divide both sides by -3 to get y= -(17/3)

There are at least 2 other ways to solve this. This is just two ways. The solution will ALWAYS be the same if you have done it correctly. Y will always = to -(17/3)

7) Find the area of the shaded region:
aleksandr82 [10.1K]

Answer:

B

Step-by-step explanation:

The area of the biggest rectangle =

(9x - 2)(2x + 7) = 18 {x}^{2}  + 63x - 4x - 14  = 18 {x}^{2}   + 59x - 14

The area of the of the smallest rectangle inside=

3x(x + 12) = 3 {x }^{2}  + 36x

Then the area of the shaded region =

18 {x}^{2}  + 59x - 14 - (3 {x}^{2}   + 36x)    = 18 {x}^{2}  + 59x - 14 - 3 {x}^{2}  - 36x = 15 {x}^{2}  + 23x - 14

So, we choose B.
