<span>The correct answer is 216x</span>⁶<span>y</span>⁵<span>.
Explanation:
The first thing we do is raise the last monomial to the third power.
(4xy)(2x</span>²<span>y)(3xy)</span>³
<span>=(4xy)(2x</span>²<span>y)(3</span>³<span>x</span>³<span>y</span>³<span>)
=4xy(2x</span>²<span>y)(27x</span>³<span>y</span>³<span>).
Now we can multiply the first two monomials. When we multiply powers with the same base, we add the exponents:
8x</span>³<span>y</span>²<span>(27x</span>³<span>y</span>³<span>).
We multiply these last two monomials, again adding the exponents:
216x</span>⁶<span>y</span>⁵<span>.</span>
Hey there!!
Always remember -
wave length = velocity / frequency
Now substitute the values
Wave length = 10 / 4
Wave Length = 2.5 m
Answer:
-31.2x + 28.7y + 10.5
Step-by-step explanation:
Step 1: Write expression
2.5(4.2 + 7.4y) - 3.6(8x - 4.5y) - (2.4x + 6y)
Step 2: Distribute
10.5 + 18.5y - 28.8x + 16.2y - 2.4x - 6y
Step 3: Combine like terms
-31.2x + 28.7y + 10.5
3° and 177°
supplementary angles sum to 180°
let x be an angle then the other angle is 59x
x + 59x = 180
60x = 180 ( divide both sides by 60 )
x = 
= 3
the angles are 3° and (59 × 3 )= 177°
60 seconds in a minute, right? try to use that. I hope that helps...
