Length of base of the top triangle = 23 inches
Length of height of the top triangle = 47 inches
Area of the top triangle :





Thus, area of the top triangle = 540.5 sq.inches
Length of base of the bottom triangle = 47 inches
Length of height of the bottom triangle = 46 inches
Area of the bottom triangle :




Area of the bottom triangle = 1081 sq.inches
Area of the total figure :
= Area of top triangle + Area of bottom triangle


Therefore, the area of the figure = 1621.5 sq.inches
Answer:
(3y + a) (b - y)
Step-by-step explanation:
3by - 3y^2 + ab - ay
3y (b - y) + a (b - y)
(3y + a) (b - y)

Answer:
Slope is 15 and y-intercept is 35.
Step-by-step explanation:
Given : The lake side marina charges a $35 rental fee for a boat in addition to charging $15 an hour for usage.
The total cost y of renting a boat for x hours can be represented by the equation 
To find : Graph the equation and interpret the slope and the y-intercept?
Solution :
The general slope form is 
where, m is the slope and c is the y-intercept.
On comparing the equation 
The slope is m=15.
The y-intercept is c=35.
Now we plot the equation
in graphing tool.
The equation is in green line passing thorough (35,0) and (-2.333,0).
Refer the attached figure below.
Answer:
3"x4
Step-by-step explanation:
The symbol for a foot is "ft", sometimes denoted by a prime(') , also, the inch is denoted by a double prime(").
Given
2 1/2inces (2.5") blue print represents 10ft living room
We are told that the dimension of the room on the blueprint is
12'x16'
Let us convert 12' to inches
So
2.5" represents 10'
X ' will be 12'
Cross multiplying
X=(2.5*12)/10
X=3"
Let us convert 16' to inches
So
2.5" represents 10'
Y ' will be 16'
Cross multiplying
Y=(2.5*16)/10
Y=4"
the dimension of the blue print is
3"x4"
