Step-by-step explanation: hope it helps
(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 number of hours that she work for the fast food is 11
The number of hours that she mowed is 5
Step-by-step explanation:
let x= hours spent mowing
y= hours spent at the food joint.
we can now form an equations from the figures given.
x+y=16...*
10.5x+4.25y=136.75...**
solving the two equations simultaneously using the substitution method or the eliminating method,
x=11 hours
y=5 hours
