Question

$$20(15+(-20))-75(5+30)+4x(-7)$$

Evaluate

$-28x-2725$

Solution Steps

Subtract $20$ from $15$ to get $-5$.

$$20\left(-5\right)-75\left(5+30\right)+4x\left(-7\right)$$

Multiply $20$ and $-5$ to get $-100$.

$$-100-75\left(5+30\right)+4x\left(-7\right)$$

Add $5$ and $30$ to get $35$.

$$-100-75\times 35+4x\left(-7\right)$$

Multiply $75$ and $35$ to get $2625$.

$$-100-2625+4x\left(-7\right)$$

Subtract $2625$ from $-100$ to get $-2725$.

$$-2725+4x\left(-7\right)$$

Multiply $4$ and $-7$ to get $-28$.

$$-2725-28x$$

Expand

$-28x-2725$

Solution Steps

Subtract $20$ from $15$ to get $-5$.

$$20\left(-5\right)-75\left(5+30\right)+4x\left(-7\right)$$

Multiply $20$ and $-5$ to get $-100$.

$$-100-75\left(5+30\right)+4x\left(-7\right)$$

Add $5$ and $30$ to get $35$.

$$-100-75\times 35+4x\left(-7\right)$$

Multiply $75$ and $35$ to get $2625$.

$$-100-2625+4x\left(-7\right)$$

Subtract $2625$ from $-100$ to get $-2725$.

$$-2725+4x\left(-7\right)$$

Multiply $4$ and $-7$ to get $-28$.

$$-2725-28x$$
