Answer: 200,000,000 or 2 million
Step-by-step explanation:
![\bf f(x) = 4(x + 7)^2(x - 7)^3\implies 0 = 4(x + 7)^2(x - 7)^3 \\\\\\ 0=(x+7)^2(x-7)^3\implies \begin{cases} 0=(x+7)^7\\ \qquad 0=(x+7)(x+7)\\ \qquad -7=x\\ \qquad -7=x\\ ----------\\ 0=(x-7)^3\\ \qquad 0=(x-7)(x-7)(x-7)\\ \qquad 7=x\\ \qquad 7=x\\ \qquad 7=x \end{cases}](https://tex.z-dn.net/?f=%5Cbf%20f%28x%29%20%3D%204%28x%20%2B%207%29%5E2%28x%20-%207%29%5E3%5Cimplies%200%20%3D%204%28x%20%2B%207%29%5E2%28x%20-%207%29%5E3%0A%5C%5C%5C%5C%5C%5C%0A0%3D%28x%2B7%29%5E2%28x-7%29%5E3%5Cimplies%20%0A%5Cbegin%7Bcases%7D%0A0%3D%28x%2B7%29%5E7%5C%5C%0A%5Cqquad%200%3D%28x%2B7%29%28x%2B7%29%5C%5C%0A%5Cqquad%20-7%3Dx%5C%5C%0A%5Cqquad%20-7%3Dx%5C%5C%0A----------%5C%5C%0A0%3D%28x-7%29%5E3%5C%5C%0A%5Cqquad%200%3D%28x-7%29%28x-7%29%28x-7%29%5C%5C%0A%5Cqquad%207%3Dx%5C%5C%0A%5Cqquad%207%3Dx%5C%5C%0A%5Cqquad%207%3Dx%0A%5Cend%7Bcases%7D)
the -7 is found there twice, so it has a multiplicity of 2
the +7 is there thrice, so it has multiplicity of 3
hold on give me a sec please
Step-by-step explanation:
and thank you
5 (7) - 3 (-8)
35 - -24
Because two negatives equal a positive the subtraction sign will change into an addition sign.
35+24
So your answer will be 59.
Hope this helped :)
