the polynomial 10x 3 + 35 x 2 -4 x -14 is Factor by grouping what is the common factor that is missing both sets of parentheses

Step-by-step explanation:

10x^3 + 35x^2 - 4x - 14

5x^2(2x + 7) - 2(2x + 7)

(5x^2 - 2)(2x + 7)

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
