Which expression would be easier to simplify if you used the commutative property to change the order of the numbers?
A. 80 + 20+ (-17)
B. (-80) + 43+ (-120)
O c. +(-3) +
O D. (-19) + (-10) +

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
