Answer:
Equation: 5 *4 ft(48 inches)=x
the actual width is 240 inches.
Step-by-step explanation:
Let x=width
Equation: 5 *4 ft(48 inches)=x
5*48=x
x=240
Therefore, the actual width is 240 inches.
Answer:
first thing you gotta do is substitute x with -1 then you do the work first you gotta know your order of operation which is PEMDAS what that stands for is perentice exponent multiplication division addition and subtraction so then what you do first is 2*-1+3 2*-1=-2+3=1 and that is the answer you are WELCOME.
Step-by-step explanation:
Answer: The volume inside is 27 cu. ft.
Step-by-step explanation:
The surface area of a cube is the area of each face of the cube added together. There are 6 faces on a cube; 54/6 = 9 sq. ft. for each face of the cube.
Each face of a cube is a square, whose area is given by A=s²:
9 = s²
Take the square root of both sides:
√9 = √s²
3 = s
Each side of the square, or edge of the cube, is 3 ft.
This makes the volume 3(3)(3) = 27 cu. ft.
Length of the rectangle = 7w
Area = length * width
A = 7w^2
