Answer:
n= 3
Step-by-step explanation:
3 (4 + n) = n + 18
you take 3x4=12
then 3x3=9 then you add 12 and 9 which would be in the ( )
12+9 = 21
then if you replace n =3 on other side and add it to 18 answer is 21
therefore both sides would equal 21 so n=3
3(4+3)=3+18
21=21
Answer:
-8
Step-by-step explanation:
-5+2-3-2
Combine
-3 -3-2
-6-2
-8
Yes, because there are two pairs of congruent corresponding angles
We know that
[volume of a prism]=L*W*H
L=3 1/2 in-------> (3*2+1)/2--------> 7/2 in
W=3 1/2 in-------> (3*2+1)/2--------> 7/2 in
H=7 in
so
[volume of a prism]=(7/2)*(7/2)*7--------> 85.75 in³
[the difference in volume between the prism and the storage container]=90-85.75------------> 4.25 in³ (4 1/4 in³)
the answer is 4.25 in³ (4 1/4 in³)
