What non-zero rational number must be placed in the square so that the simplified product of these two binomials is a binomial: $(7t-10)(5t+\Box )$? Express your answer as a mixed number.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

probably .5

i can on others if necessary.
