Answer:
(b) {-8, 2}
Step-by-step explanation:
The given equation
x³ +6x -16 = 0
cannot be factored in integers. It has one irrational real root near x=1.759, and two complex roots.
__
Perhaps you want to factor ...
x² +6x -16 = 0
(x +8)(x -2) = 0
This has solutions x = -8 and x = 2 that make the factors be zero.

"Cubed" refers to an exponent of 3.
0 = 3x² + 2x - 2
Perfect example of a leading coefficient (coefficient of the highest degree term) of 3 and a constant term (degree zero) of -2. CHECK ME
0 = -2 - 3x² + 3
That has a leading coefficient of -3 and a constant of -2+3=1, so don't check me.
0 = -3x + 3x² - 2
CHECK ME. The order we write the terms doesn't matter; the leading coefficient is on the highest degree, 3x² here. The constant is -2.
0 = 3x² + x + 2
The leading coefficient is indeed 3 but the constant is a positive two, don't check me.
0 = -1x - 2 + 3x²
CHECK ME. Again, the written order of the terms doesn't matter; it's the degree that matters.
Answer:
4930
Step-by-step explanation:
10 + 7
17 x 20 x 12
4080
10 + 7
17 x 5 x 10
850
850 + 4080
Area = 4930

A parallelogram is a shape with 4 sides where the 2 opposite sides are congruent or has the same measurements. The perimeter of a parallelogram is expressed as:
P = 2l + 2w
We take AD as the length, l, and AB as the width, w.
92 = 2(2w + 7) + 2w
92 = 4w + 14 + 2w
78 = 6w
w = 13 cm
l = 2w+7 = 33 cm
