Answer:
Step-by-step explanation:
f(x)=4x+1 and g(x)=x^2+5,
(f+g)(x) = f(x) + g(x) = 4x+1 + x²+5
(f+g)(x) = x² +4x+6
Which is the side length of a cube with a volume of 64 m3?
<em>Volume: 64m</em>³
a^3 = 64
<span>\sqrt[3]{64}</span> [/tex] = 4 m
↑
the answer
Check
4 * 4 * 4 = 64 m³
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
-------------------------
using pythagorean theorem
a^2 + b^2 = c^2
(12x)^2 + (16x)^2 = 10^2
square each term
144x^2 + 256x^2 = 100
combine like terms
400 x^2 = 100
divide by 400 on each side
x^2 = 1/4
take the square root on each side
x = 1/2
Answer: x=1/2
