Julio says, If you subtract 18 from my number and multiply the difference by −4, the result is −20. What is Julios number?

Julio's number is 40

Step-by-step explanation:

"If you subtract 17 from my number and multiply the difference by negative 4, the result is negative 92.

n= number

(n-17)*(-4) = -92

distribute

-4 *n - 17*(-4) = -92

-4n +68 = -92

subtract 68 from each side

-4n +68-68 = -92 -68

-4n = -160

divide each side by -4

-4n/-4 = -160/-4

n = 40

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
