Answer:
-3y^2 + y + 100
Step-by-step explanation:
Combine like terms.
-3y+4y = 1y or "y"
Add "y" back into the equation.
-3y^2 + y + 100
The equation cannot be simplified any further.

Answer:
84 m² is the correct answer.
Step-by-step explanation:
first, split the parallelogram into three shapes: the two triangles on either side of the shape, and the rectangle in the middle.
the formula for the area of a triangle is base x height / 2. all of the measures are indicated in the picture so that means that 4 x 7 / 2 = 14. since there are two triangles, add 14 + 14 = 28.
then, find the area of the rectangle. the area of a rectangle is length x width. 8 x 7 = 56.
56 + 28 = 84.
