Answer:
21(11 +3x) or simplified more, would be: 231 + 63x
Step-by-step explanation:
P E M D A S
First, Do what is in the parethesis
7 x 3(5 x 2 + 3x + 1)
7 x 3(10 + 1 + 3x)
7 x 3(11 +3x)
Since there are no exponents move on to the next step.
Then multiply.
21(11 + 3x)
I didn't know whether if you were trying to put 5x(2) or not, so it got me confused! Sorry if this isn't right equation! But I hoped this helped!
If simplifies even more, it would be
231 + 63x
(If they wanted it to be in simpilest form)
Devisor is the bottom number
hmm
11.75=11 and 3/4
so times it by 4 to clear denomenator
but do it by top and bottom
23.4/11.75 times 4/4=93.6/47
so times it by 4/4
Substitute -8 for t in the expression, and now you have: h(-8) = -2[(-8) + 5]^2 + 4. Solve inside the parentheses; add -8 and 5.
h(-8) = -2[-3]^2 + 4, solve exponents next by squaring -3.
h(-8) = -2[9] + 4, multiply -2 and 9.
h(-8) = [-18] + 4, add -18 and 4.
h(-8) = -14.
Step-by-step explanation:
Quadratic term = Coefficient of x^2 term = 3.
