Answer:

Step-by-step explanation:

x2 + 5x + 4 (the area of the rectangle)

x + 2 (the length of one side)

(x2 + 5x + 4)/(x + 2)

do a division of this polynomial and you get; (x + 3) - 2/(x+2), you could leave the answer like this or you could simplify by using the LCM method

= [(x+2)(x+3) - 2]/(x + 2)

checking; (x + 2)*[(x+2)(x+3) - 2]/(x + 2) = (x+2)(x+3) - 2 = x2 +5x + 6 - 2 = x2 +5x + 4 (proven)

What is the factored form of x^2 - 196 ?

Luba_88 [7]

D. (x-14)(x+14)
a negative and a positive multiplied makes a negative outcome so -14•+14=-196. x•x is = to x^2

Slope is -2 and y-intercept is -6 how do I write the linear equation in slope intercept form

PtichkaEL [24]

You need to write it in the form y = mx +b
since slope is m and b is the y-intercept, it would be written as y = -2x + -6

I hope this helped :)
