Answer:

Solution:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

Answer: 3x(3x + 2)

scoray [572]
<span>Given that x represents the width of the rectangle and that the length of the rectangle is three times longer than the width. Then the length is 3x. The perimeter of a rectangle is given by 2(length + width) = 2(3x + x) = 2(4x) = 8x. The perimeter of the rectangle is 16 feet. Therefore, the required equation is 8x = 16. </span>

Your friend's swimming pool is in the shape of a rectangular prism, with a length of 25 feet, a width of 8 feet, and a height of
RUDIKE [14]

Answer:

Part a) V=1,000\ ft^{3}

Part b) h=5\ ft

Part c) =718\ gal

Step-by-step explanation:

Part a) What is the volume of your friend's swimming pool?

we know that

The volume of a rectangular prism is equal to

V=LWH

substitute the values

V=(25)(8)(5)=1,000\ ft^{3}

Part b) Your swimming pool is in the shape of a cylinder with a diameter of 16 feet and has the same volume as your friend's pool. What is the height of your pool?

we know that

The volume of a cylinder is equal to

V=\pi r^{2} h

we have

V=1,000\ ft^{3}

r=16/2=8\ ft ----> the radius is half the diameter

substitute and solve for h

1,000=\pi (8)^{2} h

h=1,000/(64 \pi)

h=1,000/(64*3.14)=5\ ft

Part c) While you were on vacation, 6 inches of water evaporated from your pool. About how many gallons of water evaporated from your pool?

remember that

1\ ft=12\ in

so

6\ in=6/12=0.5\ ft

Find the volume of water  for h=5-0.5=4.5\ ft

V=(3.14)(8)^{2}(4.5)=904.32\ ft^{3}

so

the volume of water evaporated is equal to

1,000\ ft^{3}-904.32\ ft^{3}=95.68\ ft^{3}

convert to gallons

remember that

1\ ft^{3}=7.5\ gal

so

95.68\ ft^{3}=95.68*7.5=718\ gal

Write an equivalent expression for (x - 11)(x + 9).
vodka [1.7K]

Answer:

x²-2x-99

Step-by-step explanation:

(x-11)(x+9) - foil method

x times x = x squared

x times 9 = 9x

-11 times x = -11x

-11 times 9 = -99

x squared + 9x + 11x + -99

x squared-2x-99

Jet001 [13]

Answer:

90

Step-by-step explanation:

Angle Formed Outside = 1/2(DIFFERENCE of Intercepted Arcs)

ARC LN = 360 - 270 =90

LMN  = 1/2(270 -90)

         = 1/2 (180)

        = 90
