Question

$$9x(5-y)+3(10x-4xy)$$

Evaluate

$3x\left(25-7y\right)$

Solution Steps

Use the distributive property to multiply $9x$ by $5-y$.

$$45x-9xy+3\left(10x-4xy\right)$$

Use the distributive property to multiply $3$ by $10x-4xy$.

$$45x-9xy+30x-12xy$$

Combine $45x$ and $30x$ to get $75x$.

$$75x-9xy-12xy$$

Combine $-9xy$ and $-12xy$ to get $-21xy$.

$$75x-21xy$$

Expand

$75x-21xy$

Solution Steps

Use the distributive property to multiply $9x$ by $5-y$.

$$45x-9xy+3\left(10x-4xy\right)$$

Use the distributive property to multiply $3$ by $10x-4xy$.

$$45x-9xy+30x-12xy$$

Combine $45x$ and $30x$ to get $75x$.

$$75x-9xy-12xy$$

Combine $-9xy$ and $-12xy$ to get $-21xy$.

$$75x-21xy$$
