Answer:
Surface area means all of the outside areas, kind of like when you wrap a present.
Step-by-step explanation:
1st draw the box and find the area of the top and the bottom of the figure
10 x 3 = 30 for the top and 30 for the bottom, so 60 for both.
2nd find the area of two opposite sides:
10x 4.5 = 45 for one side and 45 for the other side, which is 90 for both
3rd find the area of the last two opposite sides:
3 x 4.5 = 13.5 for one side and 13.5 for the other side, so 27 for both.
4th: now add all those sides 60 + 90 + 27 = 177 inches squared.
14a^2 - 24a + 7 - (11a^2 + 42a - 6)...distribute the negative thru the parenthesis
14a^2 - 24a + 7 - 11a^2 - 42a + 6 =
3a^2 -66a + 13 <==
- 18
2- 20
= -18
Because you do the same thing just going to end up with a negative.
answer: the denominator of the improper fraction is the sum of the numerator and the product of denominator and the whole number of the mixed fraction.
