Factor completely. 81x^2+180x+100=81x

Mathematics
1 answer:
Ilya [14]2 years ago
3 0

Answer:

There is no solution :/

Step-by-step explanation:

81x^2+180x+100=81x

Step 1: Subtract 81x from both sides.

81x^2+180x+100−81x=81x−81x

81x^2+99x+100=0

For this equation: a=81, b=99, c=100

81x^2+99x+100=0

Step 2: Use quadratic formula with a=81, b=99, c=100.

x= −b±√b2−4ac/ 2a

x= −(99)±√(99)2−4(81)(100) /  2(81)

x= −99±√−22599/162

So you see... no solution

Hope this helps!

The volume of a rectangular prism is given by the formula V=lwh, where I is the length of the prism, w is the width, and h is th
antoniya [11.8K]

Answer:

The answer is 6x^{3} +39x^{2}+54x

Step-by-step explanation:

Volume of the rectangular prism = Length * Width * Height

Length (l) = x+2

Width (w) = 3x

Height (h) = 2x+9

By substituting these values to the equation above,

Volume of the rectangular prism = (x+2)*3x*(2x+9)

                                                      =(3x^{2} +6x)*(2x+9)

                                                      =6x^{3} +27x^{2} +12x^{2} +54x

                                                      =6x^{3} +39x^{2}+54x

Therefore,

The answer is 6x^{3} +39x^{2}+54x

The length of a rectangular poster is 2 more inches than three times its width. The area of the poster is 33 square inches. Solv
laiz [17]

Answer:

Step-by-step explanation:

Area of the rectangle = 33 inches sq

Area of a rectangle (formula) = l*b

let the width be x

length = 2 inches + 3x = 2+3x

Area of the rectangle = l*b = 2+3x + x

33 inches sq = 2+3x + x

33 in sq = 2+4x

33/2 = 4x

16.5/4 = x

x = 4.125

width= <u>4.125 inches</u>

length = 2+3x = 2+3(4.125) = <u>14.375</u>

<u></u>

(unless your poster is 32 sq inches and you made a mistake, just replace 33 with 32 and solve it)
