If you are implying that the number is 15ft, yes. -15 would be 15 feet below.
Answer:
x+3 will be factor of polynomial
Step-by-step explanation:
We have given polynomial ![x^4+3x^3-28x^2-36x+144](https://tex.z-dn.net/?f=x%5E4%2B3x%5E3-28x%5E2-36x%2B144)
We have to find that is x+3 is one of factor of polynomial
For this if x+3 will factor of polynomial
Then if we put x=-3 in the polynomial then the the value of polynomial will be zero
As ![P(-3)=(-3)^4+3\times (-3)^3-28\times (-3)^2-36\times -3+144=81-81-252+108+144=0](https://tex.z-dn.net/?f=P%28-3%29%3D%28-3%29%5E4%2B3%5Ctimes%20%28-3%29%5E3-28%5Ctimes%20%28-3%29%5E2-36%5Ctimes%20-3%2B144%3D81-81-252%2B108%2B144%3D0)
So x+3 will be factor of polynomial
Answer:
x = 175
Step-by-step explanation:
Add 8 on both sides to get 350 = 2x. Divide 2 on both sides to get your x value which is 175.
Cancel x^2
Divide by 4
9/(16y)
