An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 9 more than three times the length of the bottom of the triangle. The last side is 9 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle. What is the expression for the perimeter of the triangle?
Answer:
The perimeter of the triangle can be expressed as 5x + 18.
Step-by-step explanation:
Perimeter of an object is the sum of the length of its sides.
For the required triangle, we have;
length of the base = x
length of the second side = 3x + 9
length of the third side = x + 9
Perimeter of the triangle = length of the base + length of the second side + length of the third side
= x + (3x + 9) + (x + 9)
= x + 3x + 9 + x + 9
= 5x + 18
The perimeter of the triangle can be expressed as 5x + 18.

15.it will take 88 minutes to add 16 seats.
It will take 104.5 minutes to add 19 seats.
Step-by-step explanation:
Let m represent number of minutes.
We have been given that an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle to a rate of 2 seats in 11 minutes.
We will use proportions to solve our given problem.
To find the time taken to add 16 seats, we will in our proportion as:
Therefore, it will take 88 minutes to add 16 seats.
To find the time taken to add 19 seats, we will in our proportion as:
Therefore, it will take 104.5 minutes to add 19 seats

Find the perimeter of the figure below.
13 ft
12 ft
Figure not drawn to scale
Perimeter______ Ft
Answer:
P=50
Step-by-step explanation:
First use the formula for perimeter which is P = 2l + 2w. Then plug in to find your answer.
STEPS:
P = 2l + 2w
P=2(13)+2(12)
P=26+24
P=50

9514 1404 393
Answer:
-24
Step-by-step explanation:
We can simplify this to ...
b^2 +3(b -b^2) -2a
= b^2 +3b -3b^2 -2a
= -2b^2 +3b -2a . . . . . . . simplified form
This can be made easier for evaluation by factoring out b.
= (-2b +3)b -2a
Using the given values, this is
= (-2(4) +3)(4) -2(2)
= (-5)(4) -4

parallelogram has vertices at (4,4), (7,4), (5,2), and (2, 2). The parallelogram is translated 7 units down and reflected across the y-axis. What are the coordinates of the first point of its image (4,4)?
Answer:
Step-by-step explanation:
So we move the parallelogram down 7 units and get the coordinates: (-3,4) (0,4) (-2,2) (-5,2)
Then the equation for reflecting across the y-axis is (x,y) ---> (-x,y) Then I think you can solve it from there. Just take the x points and make them the opposite charge.
If the expression 76.56 is written as 6k, what is the value of k?
Answer:
6k=76.56
k = 12.76
Step-by-step explanation:
the total value of 76.56 is represented as 6k
this means we equate 6k to 76.56
i.e 6k = 76.56
dividing both sides by 6
we have, k = 12.76
