<span>3(7x+ 1) = 21
21x + 3 = 21
21x = 18
x = 6/7
hope this helps!</span>
Remember please that Diagonals of a Rectangle are equal to each other:<span>
3y/5 = 3(y-4)
So
</span><span>3y = 15(y-4)
3y = 15y - 60
60 = 12y
y = 5 Diagonals are both 3 units
With that you will be able to know which is the answer from your options</span>
V=LWH (multiply the length, width and height)
So plug in the numbers, V=6x14x10=840 ft^3 (feet cube)

P(1) = 37,100
P(4) = 58,400
The linear equation (for x ≥ 1)
P(x) = 37,100 + a(x-1)
For x = 4
58,400 = 37,100 + a(4-1)
58,400 - 37,100 = 3a
21300 = 3a
a = 7100
So, the linear equation:
P(x) = 37100 + 7100*(x-1)
P(x) = 37100 + 7100x - 7,100
P(x) = 7100x + 30000
To find when the profit should reach 108100, we can substitute P(x) by 108100.
108100 = 7100x + 30000
108100 - 30000 = 7100x
78100 = 7100x
x = 78100/7100
x = 11
