We solve for the area of the original triangle and solution is shown below:
Original triangle area = LW = 5*10 = 20 squared units
If we extend this x on one side that resulted to L-shaped, we have the new area such as shown below:
New area = (L+X) (W)
126 = (5+x) * 10
126/10 = 5+x
12.6 - 5 = x
7.6 =x
I. The equation that could be used to solve for x is below:
126 = (5+x)*w
II. We arrived on this because of the statement that "x is added to one side that resulted to L-shaped rectangle, therefore it is added on 5 ft side"
III. The value of x is equal to 7.6 ft.
The answer is y=-1/2x + 5/8
x^3 − 2y^2 − 3x^3 + z^4
Plug in 3 for x, 5 for y, and -3 for z (given)
(3)^3 -2(5^2) - 3(3^3) + (-3)^4
Simplify
(3)^3 = 3 x 3 x 3 = 27
-2(5^2) = -2 x 25 = -50
-3(3^3) = -3 x 27 = -81
(-3)^4 = -3 x -3 x -3 x -3 = 9 x 9 = 81
Combine all the terms
27 + (-50) - 81 + 81
27 - 50 - 81 + 81
-23 + 0
-23
-23, or (C) is your answer
hope this helps

Answer:
A. -1 ≤ x ≤ 3
Step-by-step explanation:
The range is the horizontal extent of the graph--the set of x-values for which the function is defined. Here, the graph extends from x = -1 to x = 3, with both end points included. The range is ...
-1 ≤ x ≤ 3
