Answer:
D. Subtract 4 from both sides
Explanation:
I just learned about quadratic equations in school. The first step of solving quadratic equations is to make sure it is in standard form and equal to 0.
Standard form:
ax^2 + bx + c = 0
A = L * W
A = 50
L = 2W
50 = W(2W)
50 = 2W^2
50/2 = W^2
25 = W^2
sqrt 25 = W
5 = W
L = 2W
L = 2(5)
L = 10 <==length is 10 yd
It would come out to be $41.8275, so if you round it would cost $41.83.
334.54 + 198 = 532.54 grams total
hope this helps
Answer:
Table C
Step-by-step explanation:
To find the constant of proportionality, you need to divide y by x
Table A has a constant of proportionality of
