32 cups
It is thirty two cups because that’s how many are in 2 gallons
I think you can solve it by
=(x^2 - y^2) *( x^2 + y^2)
= (x -y)*(x+y)*(x^2 + y^2)
Answer:
7) Right triangle
8) Acute
9) Right triangle
10) obtuse
Step-by-step explanation:
Answer: The perimeter of the largest triangle = 117 units.
Step-by-step explanation:
Sides of smaller triangle = 10,20 and 15 units
Longest side = 20 units
Longest side of larger triangle = 52 units
Sides of two similar triangles are proportional.
Let k be proportionality constant.
![k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B%5Ctext%7BLength%20in%20larger%20triangle%7D%7D%7B%5Ctext%7BLength%20in%20smaller%20triangle%7D%7D)
![k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B52%7D%7B20%7D%5C%5C%5C%5C%5CRightarrow%5C%20k%3D%5Cdfrac%7B13%7D%7B5%7D)
Length of other two sides,
![10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}](https://tex.z-dn.net/?f=10%5Ctimes%5Cdfrac%7B13%7D%7B5%7D%2C%2015%5Ctimes%5Cdfrac%7B13%7D%7B5%7D%5C%20i.e.%5C%2026%5Ctext%7B%20units%7D%2C%2039%5Ctext%7B%20units.%7D)
So sides of larger triangle = 52 units, 26 units , 39 units
Perimeter of largest triangle = 52 +26+39 = 117 units
Hence, the perimeter of the largest triangle = 117 units.
