Answer:
34,000 hope it helps
Step-by-step explanation:
3x^2 + 4x - 21x - 28
x(3x + 4) - 7(3x + 4)
(3x + 4) (x - 7)
Answer: B).
Answer:
h = 3.6
Step-by-step explanation:
This is just substituting in for variables and solving for x. The hard part is knowing the formula.
R = h((a+b)/2) where a and b are the 2 different bases, h is the height or latitude, and R is the area of a trapezoid, is the formula.
Given that R = 8.1, a = 1 and b = 3.5, we can substitute these equations in the formula.
(8.1) = h(((1) + (3.5)) / 2)
= h((4.5) / 2)
= h(2.25)
8.1/2.25 = h
3.6 = h
<h3>The constant of variation is

</h3><h3>The equation is

</h3>
<em><u>Solution:</u></em>
Given that,
The conversion of square feet to square yards can be represented by direct variation
Let y represent the number of square yards
Let x be the number of square feet

y = kx ------ eqn 1
Where, "k" is the constant of variation
Three square yards are equivalent to 27 square feet
Substitute, y = 3 and x = 27 in eqn 1

Thus the constant of variation is 
<em><u>What is the equation representing the direct variation?</u></em>
Substitute k = 1/9 in eqn 1

Thus the equation is found
