Answer:
C = (13.75 * B * H)/3750
Step-by-step explanation:
The area of a triangle is represented by the equation A = 1/2 * B * H
Every time another 3750 square feet is covered, $27.50 is spent. So, we can represent the cost using the equation C = A/3750 * 27.50
Plugging in the base and height, C = (1/2 * B * H * 27.50)/3750
C = (13.75 * B * H)/3750
You can use zero as a starting point and then plot based on the direction of your number, so say you have a -1. You would plot that -1 to the left of 0 and any other negative numbers you have. Regarding positive numbers, they would all go to the right of zero so if you had to plot +1 you would plot that to the right of zero. I attached a photo to help you :)
Simplify step by step
x^2 + 4x + 2x + 8
combine like terms
x^2 + 4x + 2x + 8 = (x^2) + (4x + 2x) + (8)
= x^2 + 6x + 8
Answer: x^2 + 6x + 8
To Factor:
Factor X^2 + 4X + 2X + 8
X^2 + 6X + 8
= (X + 2)(X + 4)
Answer: = (X +2 )(X +4)
Hope this helps!!!!
The answer is 112.5 miles in 90 minutes
To create a table you can do
50:40
100:80
112.5:90
We can find the answers by multiplying the original ratio 50:40 by 2.25 we do this because 90 minutes is 2.25 times longer than 40 minutes.
