13 = r/12, first to cancel 12 and leave r alone you multiply it by 12 and it cancels and whatever you do on one side you do to the other. So you multiply 13 times 12 too.
You are then left with, 13•12 = r
Which is 156
Therefore,
r = 156
Answer:
Step-by-step explanation
they answer would be a whole number because you are multiplying by one thousand
Answer:
61.5 cm^3
Step-by-step explanation:
24:56 = 3:7
You can simplify it by dividing with 2
You could solve all the equations to see if a letter matches the question's request if you're into trail and error. Simply multiply each integer in one pair of parentheses by each individual in another, a box could help you with this (like a box in third grade showing what numbers shown on one side multiplied by numbers on the intersecting side are)

The answer: If you're looking for the answer, continue below
The answer would be "B";
(x-2)(x^2+2x+4) could be rearranged into..
-2(x^2+2x+4) + x(x^2+2x+4) when, when distributed is..
(-2x^2-4x-8) + (x^3+2x^2+4x) which is then added..
x^3+8
There was some additional simplifying and adding, but you should understand it.
