Answer:
Tamara incorrectly factored the whole expression.
Step-by-step explanation:
Note that
- 21x=3·7·x;
- 56xy=2·2·2·7·x·y.
Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.
Thus,
21x+56xy=7x(3+8y).
Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.
Answer:
none of those answers are right, because the base of the triangle at 7/24 ft (or 0.29 ft) is smaller than the height 1/3 ft (or 0.33 ft)
Step-by-step explanation:
7/24 - 1/3 =
7/24 - 8/24 = -1/24
First we have to get x by itself, so we multiply two on each side,
then we get 5x=660/4, I like to simplify here, so I would change it to 5x=165, then we divide each side by 5
x=33
:)
bearing in mind that parallel lines have the same exact slope, then any parallel line to the one above will have the same slope as that one.
