Answer:
4ab
Step-by-step explanation:
4(-3b)(+a)+8ab÷2a×4a
4(-3ab)+8ab÷2a×4a
-12ab+8ab÷2a×4a
-12ab+4b×4a
-12ab+16ab
16ab-12ab = <u>4ab</u>
Answer:
5115
Step-by-step explanation:
First of all, we need to assume there is a typo involved, and that the expression is supposed to be ...

The values being summed look a lot like the general term of a geometric sequence:

The exponents in the sum range from 1 to 10, so the values being summed range from 5/2 to 5/1024. In order for that to be the case with our general term, for r = 1/2, we must have a1 = 5/2 as we let n range from 1 to 10.
The sum of the terms of the geometric sequence is ...

The numerator of the fraction is ...
x = 5115

Hey there :)
3 ( 2t + 1 )
We use what is called the distributive property to get rid of the parenthesis
We multiply the term outside the parenthesis by all terms inside
3 ( 2t ) + 3 ( 1 )
6t + 3 → Your answer
Answer:



Step-by-step explanation:
Given

Required
Determine f(-1); f(0) and f(2)
Solving f(-1)
In this case, we simply take x as;

Substitute -1 for x in 

Apply law of indices


Solving f(0)
In this case, we simply take x as;

Substitute 0 for x in 



Solving f(2)
In this case, we simply take x as;

Substitute 2 for x in
