Answer & Step-by-step explanation:
<em>(x² - 5x)(2x² + x - 3)</em>
Multiply each term from the first expression into the second expression.
<em>2x⁴ + x³ - 3x² - 10x³ - 5x² + 15x</em>
Combine like terms.
<em>2x⁴ - 9x³ - 8x² + 15x</em>
So, after you multiply the expressions, your answer will be 2x⁴-9x³-8x²+15x.
Same as original, density = mass / volume, cutting the block in two pieces or any number of pieces doesn't change the density as ratio m/v remains constant.

Answer:
4/3 of an hour, or 1.33 hours
Step-by-step explanation:
It took Mike 1/3 of an hour to mow 1/4 of the yard. This means when it has been 1 full hour, he would have mowed 3/4 of the yard, because 
hour. Because of this, we can multiply 1/3 by 4, because he has to mow 4 parts of his lawn, and he can do 1 part in 1/3 of an hour.
