The sum of two polynomials is –yz2 – 3z2 – 4y + 4. if one of the polynomials is y – 4yz2 – 3, what is the other polynomial? –2yz2 – 4y + 7–2yz2 – 3y + 1–5yz2 + 3z2 – 3y + 13yz2 – 3z2 – 5y + 7

The first polynomial is and let the second polynomial be P(y,z).

If the sum of two polynomials is , then .

Take the first polynomial from the left side to the right side:

.

the second polynomial is .

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

this is not the answer this is just a question. is this middle school math?
