(11 + 21) - ( 3 - 100 )
= 32 + 97
= 129
or (11+21)-(3+100)
= 32 - 103
= - 71
I have no idea about your topic but hope it's right! Good luck
Answer:
Step-by-step explanation:
abc
The answer is C.
The expression is telling you to multiply the parenthesis times four. When you multply two numbers, 
, it means that you're considering 
"copies" of 
, or if you prefer, repeated times.
So, you have
<- this is twice as much as the parenthesis
<- this is three times as much as the parenthesis
<- this is four times as much as the parenthesis
Answer:
See below
Step-by-step explanation:
we have f(x) = -(x-7) + 3
and we want to find f(4)
essentially, f(4) means that the input is 4 and to find the output we plug in the value of the input where ever x is and evaluate.
So for f(x) = -(x-7) + 3
To find f(4) we replace all x's with 4
f(4) = -(4-7) + 3
we now evaluate
==> subtract 7 from 4
f(4) = -(-3) + 3
==> apply two negative rule ( basically if there are two negative signs they cancel out and the number turn positive )
f(4) = 3 + 3
==> add 3 and 3
f(4) = 6
