What is the answer for -5x^2=-500 by factoring the quadratic equation?

x=10

Step-by-step explanation:

I think..i tired

Divide both sides by 55.

{x}^{2}=-\frac{500}{5}x2=−5500

2

Simplify  \frac{500}{5}5500  to  100100.

{x}^{2}=-100x2=−100

3

Take the square root of both sides.

x=\pm \sqrt{-100}x=±√−100

4

Simplify  \sqrt{-100}√−100  to  \sqrt{100}\imath√100ı.

x=\pm \sqrt{100}\imathx=±√100ı

5

Since 10\times 10=10010×10=100, the square root of 100100 is 1010.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
