Find two numbers which differ by 4 and whose products is 45​
Dominik [7]

Answer:

5, 9

Step-by-step explanation:

let

x= first number

y = second number

x- y= 4( equation 1)

xy=45( equation 2)

From equation 1

x= 4+y( equation 3)

put equation 3 into equation 2

( 4+y)y=45

4y+y^2=45

( y-5)(y+9)=0

y=5,-9

Then put y=5 into equation 3

x=9

Given f(x) = 4x3 − 12x2 + 40x + 12, find f(–2).
Sergio039 [100]

Hey there! :)

Answer:

f(-2) = -148.

Step-by-step explanation:

To calculate f(-2), simplify substitute -2 for x in the equation. Therefore:

f(x) = 4x³ -12x² + 40x + 12

Becomes:

f(-2) = 4(-2)³ - 12(-2)² + 40(-2) + 12

Simplify:

f(-2) = 4(-8) - 12(4) - 80 + 12

f(-2) = -32 - 48 -80 + 12

Finally, you get:

f(-2) = -148.
