Answer:
Step-by-step explanation:
x² + (x + 17)² = 25²
x² + x² + 34x + 289 = 625
2x² + 34x - 336 = 0
x² + 17x - 168 = 0
x = (-17 ±√(17² - 4(1)(-168))) / (2(1))
x = 7 or - 24 the negative distance makes no sense, but if we plug our good answer of 7 ft in for the base length, the height comes out to be + 24 ft
base = 7 ft
height = 24 ft
The value of x is 5/6 and y is 8/5.
Step-by-step explanation:
Given,
12x+15y=34 Eqn 1
-6x+5y=3 Eqn 2
Multiplying Eqn 2 by 2
![2(-6x+5y=3)\\-12x+10y=6\ \ \ Eqn 3](https://tex.z-dn.net/?f=2%28-6x%2B5y%3D3%29%5C%5C-12x%2B10y%3D6%5C%20%5C%20%5C%20Eqn%203)
Adding Eqn 1 and 3
![(12x+15y)+(-12x+10y)=34+6\\12x+15y-12x+10y=40\\25y=40](https://tex.z-dn.net/?f=%2812x%2B15y%29%2B%28-12x%2B10y%29%3D34%2B6%5C%5C12x%2B15y-12x%2B10y%3D40%5C%5C25y%3D40)
Dividing both sides by 25
![\frac{25y}{25}=\frac{40}{25}\\y=\frac{8}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B25y%7D%7B25%7D%3D%5Cfrac%7B40%7D%7B25%7D%5C%5Cy%3D%5Cfrac%7B8%7D%7B5%7D)
Putting y= 8/5 in Eqn 1
![12x+15(\frac{8}{5})=34\\12x+3*8=34\\12x+24=34\\12x=34-24\\12x=10](https://tex.z-dn.net/?f=12x%2B15%28%5Cfrac%7B8%7D%7B5%7D%29%3D34%5C%5C12x%2B3%2A8%3D34%5C%5C12x%2B24%3D34%5C%5C12x%3D34-24%5C%5C12x%3D10)
Dividing both sides by 12
![\frac{12x}{12}=\frac{10}{12}\\x=\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B12x%7D%7B12%7D%3D%5Cfrac%7B10%7D%7B12%7D%5C%5Cx%3D%5Cfrac%7B5%7D%7B6%7D)
The value of x is 5/6 and y is 8/5.
