Which expression can you simplify by combining like terms?
A. 6d2+5cd−3dc+8
B. 12c2−8d2c+3dc+4
C. 7d2−3c2+6d−c
D. 16c2+8cd+7c−8d

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

the answer is c 150

step-by-step explanation:

the answer is 8.64

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
