Answer:
qn 10. 15mn² - 23m²n +4m³
Step-by-step explanation:
1. distribute 4m through the parenthesis
8mn² - 12m²n + 4m³ - 2n(5m² - 3nm) + nm(n-m)
2. use the commutative property to reorder the terms
8mn² - 12m²n + 4m³ - 2n(5m² - 3mn) + mn(n - m)
3. distribute -2n through the remaining parenthesis
8mn² - 12m²n + 4m³ -10m²n + 6mn² + mn² - m²n
4. collect like terms
8mn² + 6mn² + mn² - 12m²n - 10m²n - m²n + 4m³
5. complete bodmas
15mn² - 23m²n +4m³
that's is how you do it so the answer is
15mn² -23m²n + 4m³
Im going to assume that 3√ is √3
And √3 is irrational because You cant square root it without getting nuked with a Random Number generator of decimals.
Answer:
4x^3+4x^2+4x+8
Step-by-step explanation: find (g+f)(4)
g(x)=3x+2
f(x)=x^3+x^2-2x
______________________
(4)*(3x+2+x^3+x^2-2x)
(4)(x^3+x^2+x+2)
4x^3+4x^2+4x+8
Answer: 15.1
Step-by-step explanation:
This is the formula<em> w=a/l </em>
so...
433.37/28.7=15.1
