Answer: 
Step-by-step explanation:
Given term: 
<em>In algebra, like terms are the terms which have the same variables with same powers. </em>
Here the variables are a and d, where d has power 3.
From the given options is the right answers as it has the same variables and power.
Rest of other options are unlike terms to the given term.
Answer: 8(3-2x)(x+5), -16x^2-56+120, x=-5, or x=3/2.
Step-by-step explanation:
First convert the multi fraction into multiplication: 8(3-2x)(x+5)
Then simplify: -16x^2-56+120
If you want, you can solve for x, which gets you x=-5, or x=3/2.
I hope this helps! :P
Divide 7 by 49 which would be 7 then add two to each cabin
Explanation: Here we have function f(x) = 2x - 5
and we're asked to find f(x - 1).
Don't be thrown off if you're asked to plus a variable into a function.
If f(x) = 2x - 5, then f(x - 1) = 2(x - 1) - 5.
<em>Remember to use parenthses when substituting into a function.</em>
So simplifying on the right side, we would distribute the 2
through the parenthses and we have 2x -2 - 5.
Now combining like terms, we have 2x - 7
