Answer:
42 inches
Step-by-step explanation:
Im guessing that the the table looks like this:
Width Length
3 7
6 14
9 21
So we can see the numbers on the right are increasing by 3 and the numbers on the left are increasing by 7.
The width is 3 times some number, and the length is 7 times the same number.
So if the width was 18 then we know the number would be 3 because 3 * 6 = 18
If that number is 6, then the length will be 6 * 7 = 42
So the length is 42 inches
So, what is the total lenght of the pieces that wer cut off?
we multiply the lenght by the number:
4

*5=20+

=21

and we subtract this from the original pipe, that is
30

-21

we need to bring the two fractions to the same denominator (by multiplying the fraction art in the first by 3 and 4 the second):
30

-21

=9

so the correct answer is D!
Answer:
(2,0) and (2,-2)
Step-by-step explanation:
y+3<2x
(2,0) is solution because 0+3<2*2, 3<4 and
(2,-2) because - 2+3<2*2, 1<4
