Answer:
168/(x² +7x)
Step-by-step explanation:
The height of each window is 14/(x+7), and the width of each window is 12/x. The area of each window is the product of its height ans width:
area = (14/(x+7))(12/x) = 168/(x(x +7))
area = 168/(x² +7x)

<em>Comment on the problem</em>
There is not enough information given to determine suitable values for x. If x is 42, each window is a square 3 3/7 inches on a side.
Answer: y=−2x+1
Step-by-step explanation:
Answer:
y = -4/3 x=-1/3
Step-by-step explanation:
y = x2 + 2x – 3 and y = x – 1
y= (y + 1)2 + 2(y + 1) - 3 and x= y+ 1
y= 2y + 2 + 2y +2 and x= y+ 1
-3y = 4 and x= y+ 1
y = -4/3 and x = (-4/3) + 1 = -1/3
x2 is x squared or x multiplied by two
Answer:
Step-by-step explanation:
Let x represent the length of the shorter base in inches. Then the longer base has length x+6. The area of the trapezoid is given by the formula ...
A = (1/2)(b1 +b2)h
Filling in the values we know, we have ...
48 = (1/2)(x +(x+6))(6)
16 = 2x +6 . . . . . divide by 3
10 = 2x . . . . . . . . subtract 6
5 = x . . . . . . . . . . divide by 2
(x+6) = 11 . . . . . . find the longer base
The lengths of the bases are 5 inches and 11 inches. We found them by solving an equation relating area to base length.
3.7 x 4.1 x 10 = 151.7 cm2
