Answer:
(A) 49
Explanation:
Most of the equation is just explaining what length and width is.
Area = L (length) · W (Width)
Option One:
Length: 9
Width: 5
9 · 5 = 45
There is no option for 45 so we need to check option two.
Option Two:
Length: 7
Width: 7
7 · 7 = 49
There is an option for 49, so that is our answer.
Basically, they are just explaining that Area = L · W, and to check both options to see if there is an answer.
Answer:
The height of the mural is 10.2 feet.
Step-by-step explanation:
The general formula for the area of a rectangle is A = LW, where A = area, W = width and L = length (height in this example). Since we know the values of both area and width, we can plug these numbers into the formula and solve for the missing variable 'L': 128.52 = 12.6L. Using inverse (opposite) operations to isolate the variable and solve, we would divide each side of the equation by 12.6: 128.52/12.6 = 12.6L/12.6 or L = 10.2. So, the height of the mural would be 10.2 feet.
Slope = (change in 'y') / (change in 'x')
If you find two points where the line goes through the corners of boxes,
then count up the 'y' boxes and the 'x' boxes between those two points,
you'll find that the line rises 3 y-boxes for each x-box.
The slope of the line is 3 .
