3x^2-19x-14



Explanation:

You need to multiply each number in the parenthesis by the other numbers in the parenthesis then combine like terms



(X-7)(3x+2)

3x*x=3x^2
-7*3x=-21x
X*2=2x
-7*2=-14

So you have 3x^2-21x+2x-14
Then you would add -21x+2x and you get -19x

So your final answer would be:

3x^2-19x-14

Please help<br> Solve for x.
Olegator [25]
Sum of interior angles = (n-2) × 180<span> = (5-2) x 180 = 3 x 180 = 540

so
x + 90 + 107 + 144 + 138 = 540
x + 479 = 540
x = 540 - 479
x = 61</span>
