they easiest way to find the right answer is to look at the 2 first terms and checking if they equal 64x³
doing so:
A:
48x³+...
B:
64x³+...
C:
9x³-48x³+...
= -39x³+...
-> the answer should be B, to make sure this is the right answer, you can just solve B
B:
(4x+3)(16x²-12x+9)
= 64x³- 48x²+36x+48x²-36x+27
= 64x³+27
-> answer B is correct
Answer:
12
Step-by-step explanation:
Convert the 3 liters into milliliters and then divide it normally or in the fraction way
Simple, take 3 1/2 turn it into a decimal which = 3.50 since
1/2 = 0.5 because 1 divide by 2 = 0.5
Same thing for 1 1/4 = 1.25 since
1/4 = 0.25 because 1 divide by 4 = 0.25
3.50 divide by 1.25 = 2.8 miles one hour.
Answer:
41%
Step-by-step explanation:
Convert to inches and do the percent thing
-4(x+8)+25≤-2+1(x-50)
-4x-32+25≤-2+x-50
-4x-x≤-2-50+32-25
-5x≤-45
-x≤-45/5
-x≤-9
x≥9
Answer: x≥9
