Pls pls pls answer! I will mark brainliest!!!! tysm<br> xy = 72<br> (x + 2)(y - 4) = 128
zheka24 [161]

Answer:

x=2 and y=36

Step-by-step explanation:

you have two equations

1) xy=72 and 2) (x+2)(y-4)=128

solve for one of the variables in equation 2), lets do y

(x+2)(y-4)=128, divide by (x+2) to both sides and add 4 to isolate variable y

therefore, y=(128/(x+2))+4

then plug in y into equation 1)

so x(our new y)=72

x( 128/(x+2) +4 )=72

distribute the x so you will get

(128/(x+2))x +4x=72

we are now solving for x, so isolate the x by subtracting 4x and multiplying by (x+2) to get

128x=(x+2)(72-4x)

multiply by distribution and combine like terms

-4x^2 -64x +144 =0

solve for x by quadratic formula, you'll get x=2 or x=-18

substitute back into equation 1), (2)(y)=72, solve for y to get 36

then you can check by substituting back into equation 2)

(2+2)(36-4)=128

(4)(32)=128, 128=128

Factor completely. f(x) = −16x2 + 22x + 3
grigory [225]

Answer:

8x(2x+3)-2(x+3)

step by-step explanation:

16x^2+22x+3

16*3=48

2 numbers which have a product of 48 and a sum of 22

=24 and -2

Rewrite the centre term as these two numbers, so

16x^2+24x-2x+3

Factorise each pair of terms.

8x(2x+3)-2(x+3)
