Step-by-step explanation:
im assuming that its an equalateral triangle because it makes the problem easier.
if you use the midpoint of the base as the point of where to make the parallels lines and draw them, you can easily find 4 congruent triangles, the side length of one of these congruent triangles is 2.5, and summing up the perimeter of the quadrilateral, you get 10.

Two cars got an oil change at the same auto shop. The shop charges customers for each quart of oil plus a flat fee for labor. The oil change for one car required 5 quarts of oil and cost $22.15. The oil change for the other car required 7 quarts of oil and cost $25.15. How much is the labor fee and how much is each quart of oil?
Answers
Answer:
Labor = $14.65
Step-by-step explanation:
25.15-22.15= 3 3/2 = 1.5
1qt = $1.5
1.5 x 5 = $7.5
22.15 - 7.5 = $14.65
1.5 x 7 = 10.5
25.15 - 10.5 = $14.65
Labor = $14.65

Give the domain and range of the relation then determine if the relation is a function (-3,3), (1, 1), (0, -2), (1, -4), (5, -1)
Domain:_____
Range:_____
Function?_____
PLEASE HURRY
Answers
*domain is the x-value, input, independent
Ranges: {-4, -2, -1, 1, 3}
*range is the y-value, output, dependent
LIST BOTH FROM LEAST TO GREATEST
Functions are when each input(x) has one and only one output(y)
If you were to graph a function, no points would line up vertically with one another.
This question would not be a function because an input (number 1 in this case) has more than one output (1 AND -4)
So function? No.

a=1 b=-4 c=0
2x²+6x+5=0
-2x²+x+5 identify the coefficients
Answers
Step-by-step explanation:
The general form of the quadratic equation is :
[tex]ax^2+bx+c[/tex]
The given equation is x²+4x+20=0
On comparing the given equation and the general equation, we find that
a = 1, b = 4 and c = 20
Hence, the correct option is a=1 b =4 c = 20.
If the equation is 2x²+6x+5=0, then
a = 2, b = 6 and c = 5
If the equation is -2x²+x+5
a = -2, b = 1 and c = 5
Find the value of x.
