Answer:

x^2+2x-3

Step-by-step explanation:

Note that x^2-x-20=(x-5)(x+4), so, if the denominator is (x-5)(x+4)(x+3), we need to multiply the numerator by (x+3). And (x-1)(x+3)=x^2+2x-3.

What percent of 99 is 90?
Yuri [45]

Answer:

91%

Step-by-step explanation:

We can use the formula \frac{is}{of}=\frac{percent}{100}

  • "is" is 90
  • "of" is 99
  • "percent" is what we are solving for so we will denote it as x

Substituting in our values we get \frac{90}{99}=\frac{x}{100}

  • We will need to cross multiply here to get (90)(100) = (x%)(99)
  • This simplifies to 9000 = 99x%
  • Dividing by 99 on both sides we get 90.9% → x = 91%

A cube with side length 4p is stacked on another cube with side length 2q^2. What is the total volume of the cubes in factored f
inysia [295]
Volume of the cube with side 4p = 4p x 4p x 4p = 64p³

Volume of the cube with side 2q² =  2q² x  2q² x  2q² = 8q⁶

Total Volume = 64p³ +  8q⁶

Total Volume = (4p)³ + (2q²)³

Total Volume = (4p + 2q²)( ( 4p)² - (4p)(2q²) + (2q²)²)

Total Volume = (4p + 2q²)( 16p² - 8pq² + 4q⁴)

 
Answer:  (4p + 2q²)( 16p² - 8pq² + 4q⁴)
