(x + 1 ) is not a factor of the polynomial
given (x - a) is a factor of a polynomial f(x) then x = a is a root and the remainder is f(a) = 0
evaluate the polynomial f(- 1)
f(- 1) = 2(- 1)³ - 9(- 1)² + 17(- 1) - 6
= - 2 - 9 - 17 - 6 = - 34 ≠ 0
Thus (x + 1) is not a factor of the polynomial
The third one, because she got -8 for the product's exponent by multiplying 4 and -2 instead of adding them, show the answer should have been 10^2.
Answer:
568 square ft.
Step-by-step explanation:
11x24=264
19x16=304
264+304=568
Answer:

Step-by-step explanation:
Step 1: Write out equation
d(-3 + x) = kx + 9
Step 2: Distribute
-3d + dx = kx + 9
Step 3: Subtract dx on both sides
-3d = kx - dx + 9
Step 4: Subtract 9 on both sides
-3d - 9 = kx - dx
Step 5: Factor
-3d - 9 = x(k - d)
Step 6: Divide both sides by k - d
