Answer:
The answer is x<6 I hope this helps
Step-by-step explanation:
The first step can be subtracting 2x from both sides leaving the equation with 6x + 3 = -15
Start at -4 and go over to the right 6. - is left and +is right. the answer is 2.
Answer:
f(x) = (x + 11) (x + 3) (x − 1) (x − 3)
Step-by-step explanation:
f(x) = x⁴ + 10x³ − 20x² − 90x + 99
f(x) is a fourth order polynomial, so it has 4 roots. Use rational root theorem to find possible rational roots.
±99, ±11, ±9, ±3, ±1
By trial and error, the zeros are -11, -3, 1, and 3.
f(x) = (x + 11) (x + 3) (x − 1) (x − 3)
20+20+38+38=116
116×22 = 2552
It will cost $2,552 to install the wood fence.
