Answer:
A) is 29.76 B) IS $54
Step-by-step explanation:
you have to times 24 x 24% = 5.76 then you add 24 + 5.76 =29.76
Answer:
![y = 2x + 7](https://tex.z-dn.net/?f=y%20%3D%202x%20%2B%207)
Step-by-step explanation:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
m = slope
b = y-intercept
Length of AB = 18. 92
Length of AC = 26. 15
Length of BC = 32. 552
<h3>How to determine the sides of the triangle</h3>
Using the Pythagorean theorem, we have that
![(20 x-2)^2 = (12x + 20)^2 + (25x)^2](https://tex.z-dn.net/?f=%2820%20x-2%29%5E2%20%3D%20%2812x%20%2B%2020%29%5E2%20%2B%20%2825x%29%5E2)
Expand the bracket
![400x^2- 4 = 144x^2 + 400 + 625x^2](https://tex.z-dn.net/?f=400x%5E2-%204%20%3D%20144x%5E2%20%2B%20400%20%2B%20625x%5E2)
Collect like terms
![400x^2 - 144x^2 - 625x^2 = 400 + 4](https://tex.z-dn.net/?f=400x%5E2%20-%20144x%5E2%20-%20625x%5E2%20%3D%20400%20%2B%204)
![-369x^2 = 404](https://tex.z-dn.net/?f=-369x%5E2%20%3D%20404)
Make x^2 subject
![x^2 = \frac{404}{369}](https://tex.z-dn.net/?f=x%5E2%20%3D%20%5Cfrac%7B404%7D%7B369%7D)
![x = \sqrt{1.0948}](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%7B1.0948%7D)
![x = 1. 046](https://tex.z-dn.net/?f=x%20%3D%201.%20046)
Thus,
Length of AB = 20x -2 = 20(1. 046) - 2 = 18. 92
Length of AC = 25x = 25* 1.046 = 26. 15
Length of BC = 12x + 20 = 12(1. 046) + 20 = 32. 552
