Length - l
Width - w
Given,
Perimeter = 78 ft
2(l + w) = 78
l + w = 39
l = 39 - w
Given,
l = 9 + w
39 - w = 9 + w
2w = 30
--- w = 15
--- l = 39 -w = 39 - 15 = 24
Therefore, the length of the rectangle is 24 ft and width is 15 ft.
Answer:
96mm²
Step-by-step explanation:
a√ a²+ 4h²
4 √4² + 4(12)²
4 √4² + 4 (144)
4√4² + 576
97. 2 mm²
Using linear functions, it is found that the two plans cost the same for 5000 minutes of calling.
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
For Plan A, the cost is of $25 plus an additional $0.09 for each minute of calls, hence the y-intercept is , the slope is of , and the function is:
For Plan B, the cost is of $0.14 for each minute of calls, hence the y-intercept is , the slope is of , and the function is:
The plans cost the same for x minutes of calling, considering that:
The two plans cost the same for 5000 minutes of calling.

Answer:
EGC
Step-by-step explanation:
If you look at the triangle and highlight the triangle EGA, you will see it will be equal to the same triangle on the other side which is EGC.
