Answer:
3m² + 2mn + 7n²
Step-by-step explanation:
Subtract m² + 3mn - n² from 4m² + 5mn + 6n², that is
4m² + 5mn + 6n² - (m² + 3mn - n²)
= 4m² + 5mn + 6n² - m² - 3mn + n² ← collect like terms
= 3m² + 2mn + 7n²
Answer:
The answer is t>0
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2<3t−2
Step 1: Flip the equation.
3t−2>−2
Step 2: Add 2 to both sides.
3t−2+2>−2+2
3t>0
Step 3: Divide both sides by 3.
3t
/3 > 0/3
<em><u>t>0
</u></em>
The expression that could best describe the statement would be " 40 n + 20
260.
Their ratio would be: Cookie / Donut = 4/3
Let, the amount of money earned from Donut = x
It would be: 4/3 = 375 / x
x = 375/4 * 3
x = 1125/4
x = 281.25
In short, Your Answer would be $281.25
Hope this helps!
