Write an expression that equals 24.include an exponent

4x^2 + 2y when x = 2 and y = 4

Why this equals 24:

First, plug in missing values:

4(2)^2 + 2(4)

Then, get rid of exponent and follow PEMDAS through rest of expression.

4(4) + 2(4)

16 + 8

24

And there you have it! Hope this helped :)

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
