Answer: First option.
Step-by-step explanation:
Given the equation 
, you need to substitute 
into this equation. Then:
Remember that the Addition property of equality states that:
Then, you can add "x" and 4 to both sides.
Therefore, you get the equation written in function notation, with "x" as the independent variable:
Answer:
i think the answer is 3.3
Perimeter of the base = 8 + 5 + 5 = 18 ft
Height = 7 ft
Base area = 1/2 x 8 x 3 = 12 ft²
Surface area = (18)(7) + 2(12) = 150 ft²
--------------------------------------------------
Answer: 150 ft²
--------------------------------------------------
The above answer is according to the worksheet but I will present it in another way for you to understand better.
The figure has 5 sides
-------------------------
Bottom Triangle
-------------------------
Area = 1/2 x base x height
Area = 1/2 x 8 x 3
Area = 12 ft²
-------------------------
Top Triangle
-------------------------
Top Triangle = Bottom Triangle
Top Triangle = 12 ft²
-------------------------
3 Rectangles on the sides
-------------------------
Area of 1st Rectangle = Length x Width
Area of 1st Rectangle = 7 x 5 = 35 ft²
Area of 2nd Rectangle = 7 x 5 = 35 ft²
Area of 3rd Rectangle = 8 x 7 = 56 ft²
Total area of the rectangles = 35 + 35 + 56 = 126 ft²
-------------------------
Total Surface Area
-------------------------
126 + 12 + 12 = 150 ft²
<em>(*Area of the 3 rectangles + top triangle + bottom triangle)
</em>
-------------------------
Answer: 150 ft²
