Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.
<u>Numerical Expression</u>
"Difference" indicates that we'll be subtracting 13 from 48.
48 - 13 = 35
<u>Algebraic Expression</u>
Variables represent the unknown number, in this case the difference between 48 and 13. Let d represent the difference between the two.
48 - 13 = d
35 = d
Answer:
A, D, E
Step-by-step explanation:
The perimeter is all of the sides added together
So, since a rectangle has 2 pairs of parallel congruent sides, or 2l and 2w, anything that would result in 2l+2w would be correct.
A, l+w+l+w=2l+2w
B, l*w cant be simplified more
C, 2*l*w would end up with 2l*w due to pemdas
D, 2(l+w)=2l+2w by distribution
E, (2*l)+(2*w)=2l+2w
For this problem, you need to substitute 4 in for your variable t. the original equation is S(t) and the one you need is S(4) -- in other words, evaluate this equation when t = 4.
S(4) = 9(4) - 4
S(4) = 36 - 4
S(4) = 32 is your answer.
