Answer:
they are multiplied by 9 on bottom
Step-by-step explanation:
The equation of direct proportion is y = 62x
<h3>
Direct variation</h3>
Two quantities are said to vary directly proportional to each other when an increase in one leads to an increase in the other or a decrease in one leads to a decrease in the other.
Direct variation is given by:
y = kx
where y, x are the variables and k is the constant of proportionality.
The equation of direct proportion is y = 62x

Answer:
3/8
Step-by-step explanation:
they simply combined the like terms (aka the x numbers in this case) so all that's left is 3/8
Answer:
199ft2
Step-by-step explanation:
area) H*W
(16ft×20ft)-(11ft×11ft)
=320ft2-121ft2
<h3>=199ft2</h3>
<em>ft</em><em> </em><em>square</em><em> </em><em>=</em><em>ft</em><em>2</em>
The side length has to be between 2 (=9-7) and 16 (=9+7). In both these corner cases the triangle will have collapsed to a line.
So the correct answers are B,C,D and E, and F is a corner case. Theoretically I suppose you have to count F in as a valid answer.
