(x+ 4) (x+4)
Apart of the test

x^2+8x+16

Step-by-step explanation:

this is just a big equation with nothing to harsh about it! you would multiply every single number so x*x to get x^2, 4*x to get 4x ( you get two of these so you would combine them ), and lastly 4*4 to get 16. after that, you would combine all of these together to get your equation!

hope that helped!

college

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
