Solve 3*(7.2-20)+sqrt{64}+3+2+30(-3)

$$3 \cdot ( 7.2 - 20 ) + \sqrt { 64 } + 3 + 2 + 30 ( - 3 )$$

Evaluate

$$-115.4$$

Solution Steps

Subtract 20 from 7.2 to get -12.8.

$$3\left(-12.8\right)+\sqrt{64}+3+2+30\left(-3\right)$$

Multiply 3 and -12.8 to get -38.4.

$$-38.4+\sqrt{64}+3+2+30\left(-3\right)$$

Calculate the square root of 64 and get 8.

$$-38.4+8+3+2+30\left(-3\right)$$

Add -38.4 and 8 to get -30.4.

$$-30.4+3+2+30\left(-3\right)$$

Add -30.4 and 3 to get -27.4.

$$-27.4+2+30\left(-3\right)$$

Add -27.4 and 2 to get -25.4.

$$-25.4+30\left(-3\right)$$

Multiply 30 and -3 to get -90.

$$-25.4-90$$

Subtract 90 from -25.4 to get -115.4.

$$-115.4$$

Factor

$$-115.4$$
