(3m+5n)(9m²-15mn+25n²)
1) Let's factorize 27m³ +125n³.
27m³ +125n³ <em>Let's use x³ +y³ product to factorize that</em>
<em />
x³ +y³ = (x +y)(x²-xy +y²)
2) So let's rewrite it, since 3³ = 27 and 5³ = 125
27m³ +125n³ =
Plug x =3m and y = 5n into those factors (x +y)(x²-xy +y²)
27m³ +125n³= (3m + 5n)(3²m² -5n*3m +5²n²)
27m³ +125n³= (3m+5n)(9m² - 15mn +25n²)
3) So the answer is
(3m+5n)(9m²-15mn+25n²)

Answer:
The answer is: 120.
Step-by-step explanation:
The give ratio is 5 miles for every 8 kilometers.
Multiply the ratio times 192:
5/8 * 192 =
960 / 8 = 120 Miles
Answer:
160 is the width/ hypotenuse
Step-by-step explanation:
It is real simple.
1. 7 (c+2)
2. y:5 + 4
3. 6-5 times h
4. (z+3) / 7
5. 1/2y + 9
6. (5 times g) - 4
7. 1/5c - 2
8. 8 (x-3)
9. (8 times b) + 4
10. 1/3 (z+4)
