3.33 , 4

then we will use the area=length x width formula

3.33 x 4 = 13.32 square yards

the cost of the carpet is

13.32 x 30.25 = 402.9$

How to solve x^2+x-90=0 in completing the square method

tigry1 [53]

Rearrange the equation by writing

x² + x - 90 = 0

x² + x = 90

x² + x + 1/4 = 90 + 1/4

Recall that (a + b)² = a² + 2ab + b². Then

x² + 2 • x/2 + (1/2)² = 361/4

(x + 1/2)² = 361/4

x + 1/2 = ± √(361/4)

x = -1/2 ± 19/2

x = 9 or x = -10

Help<br> I can’t get this ! Please help

Answer:

$\sqrt{2^5}$

Step-by-step explanation:

First, deal with the product of the two powers of 2 inside the parentheses.

The two factors are powers of 2, so add the exponents.

$(2^{\frac{1}{2}} \cdot 2^{\frac{3}{4}})^2 =$

$= (2^{\frac{1}{2} + \frac{3}{4}})^2$

You need a common denominator, 4, to add the fractions.

$= (2^{\frac{2}{4} + \frac{3}{4}})^2$

$= (2^{\frac{5}{4}})^2$

Now you have an exponent raised to an exponent. Multiply the exponents and reduce the fraction.

$= 2^{\frac{5}{4} \times 2}$

$= 2^{\frac{10}{4}}$

$= 2^{\frac{5}{2}}$

When a fraction is an exponent, the numerator is an exponent and the denominator is the index of the root. A denominator of 2 means a root index of 2 which means square root.

$= \sqrt{2^5}$
