Multiply.
DanielleElmas [232]

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.

A square of steel with volume 10cm3 and mass production of 75 g is cut precisely in half. The density of the two smaller pieces
shusha [124]
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.

It took Mike 1/3 hour to mow 1/4 of a yard. How long will it take him to finish the entire yard?
Kazeer [188]

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 \frac{1}{3} *3=1 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.

\frac{1}{3} *\frac{4}{4} =4/3 hours
