Answer:
Bodmas rules first -7 multiplay by 3 and get -21 the 5 multiply by 2 and get 10 ..then +10 minus 21 and get -11
Answer:
X > - 2
Step-by-step explanation:
Subtract twelve from both sides
12( - 2x < 16
- 12. -12
-2x < 4
Divide both sides by -2 to undo the multiplicstion between -2 and x
-2x < 4
÷ -2 ÷ -2
<h2>
x > -2</h2>
(when you Divide both sides of an inequality by a negative number you switch the sign to the opposite)
the answer is anna square hope this helps did this before
Answer:
f(x) = x^3 - x^2 -2x
Step-by-step explanation:
If x = a is a zero of a polynomial, then x-a is a factor of the polynomial. Given the factors of a polynomial, the polynomial can be obtained by multiplying the factors.
The factors of the given polynomial are;
x - 2
x + 1
x
Multiplying the first two factors;
(x-2)(x+1) = x^2 + x -2x -2
= x^2 -x -2
We finally multiply this result by x to obtain our polynomial;
f(x) = x ( x^2 -x -2)
= x^3 - x^2 -2x
which is a cubic polynomial since it has 3 roots.
