3 times a # (# isn't specified, so you should use a variable): 3x
result is 5: =5
Put it all together: 3x=5
96÷120 =0.8 ⇒0.8 ×100 =80 % :))
66,000*0.15
9,900*5
49,500+66000
The answer is 115.500
I'm not sure if the whole thing is correct, but here is the easier way:
66,000(1+1.15)^5
D) 1•x=5, 1•5=5 8•5=40, the answer is 40/5 CDs
E) 3/3=1, 26.25/3= 8.75. The answer is 1/8.75
F) 10/10=1, 120/10= 12. The answer is 1/12
G) 2•x=12, 2•6=12, 120•6= 720. The answer is 12/720
Hopefully this helped
(2x + y)³
(2x + y)(2x + y)(2x + y)
(2x(2x + y) + y(2x + y))(2x + y)
(2x(2x) + 2x(y) + y(2x) + y(y))(2x + y)
(4x² + 2xy + 2xy + y²)(2x + y)
(4x² + 4xy + y²)(2x + y)
4x²(2x + y) + 4xy(2x + y) + y²(2x + y)
4x²(2x) + 4x²(y) + 4xy(2x) + 4xy(y) + y²(2x) + y²(y)
8x³ + 4x²y + 8x²y + 4xy² + 2xy² + y³
8x³ + 12x²y + 6xy² + y³
