5 0

To factor the polynomial x² - 7x - 18, find two numbers whose sum is -7 and whose product is -18. Begin listing factors of -18, and those numbers' sums.

-2 × 9 = -18; -2 + 9 = 7
-9 × 2 = -18; -9 + 2 = -7

The two numbers are -9 and 2.

The factored polynomial is (x - 9)(x + 2)

Answer:
The missing factor is (x + 2)

Answer:

x = 4
WX = WY = 25
XY = 17

Step-by-step explanation:

The triangle is isosceles with side WX equal to side WY:

WX = WY

9x -11 = 7x -3

2x = 8 . . . . . add 11-7x

x = 4

Then the side measures are ...

WX = WY = 7(4) -3 = 28 -3 = 25

XY = 4(4) +1 = 16 +1 = 17

A cylinder's volume can be calculated by the formula V=Bh, where V stands for volume, B stands for base area, and h stands for h

Anastaziya [24]

Answer:

$h = 3x^5-3x^2-10\text{ units}$

Step-by-step explanation:

We are given the following in the question:

Volume of cylinder =

$V=Bh$

where B is the area of base and h is the height of cylinder.

Volume of cylinder =

$V = 6\pi x^7-6\pi x^4-20\pi x^2$

Base area =

$B = 2\pi x^2$

We have to find height of cylinder.

$h = \dfrac{V}{B}\\\\h = \dfrac{6\pi x^7-6\pi x^4-20\pi x^2}{2\pi x^2}\\\\h = 3x^5-3x^2-10\text{ units}$

Thus, the height of cylinder is $3x^5-3x^2-10$ units.
