What is the factorization of the expression below? 16x2 - 49
A. (8x + 7)(2x - 7)
B. (8x-7)(2x - 7)
C. (4x+7)(4x - 7)
O D. (4x - 7)(4x - 7)

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
