Answer: B.x^3+4x^2-19x+14 is correct
Step-by-step explanation:
(x + 7)(x2 – 3x + 2)
Multiplying both
x^3-3x^2+2x+7x^2-21x+14
x^3+4x^2-19x+14
Answer:
57
Step-by-step explanation:
the sum of those two interior angles is equal to the exterior (116), so y = 15 and the measure of angle A is 57 if you plug it in
<span>(6.45×106)⋅720,000
=</span>(6.45×10^6) * (7.2×10^5)
=46.44 ×10^11
=4.644×10^12
