Question

Perform the indicated operations 1. 2-3 x (-4) = 2-(-12)=142. 4x5+72÷(-6) = 20 + (-12)=83. 9+6_(-3)x12÷(-9)+6(-36) ÷ (-9) = 9+6 -4 = 11

Answer 1

STEP - BY - STEP EXPLANATION

Given:

1. 2-3 x (-4)

2. 4x5+72÷(-6)

3. 9+6_(-3)x12÷(-9)+6(-36) ÷ (-9)

Using PEMDAS to solve;

1)

$\begin{gathered} 2-3\times(-4) \\ \\ =2+12 \\ =14 \end{gathered}$

2)

$\begin{gathered} 4\times5+72÷\left(-6\right) \\ =20-12 \\ =8 \end{gathered}$

3)

$9+6-(-3)\times12÷\left(-9\right)+6\left(-36\right)÷-9$$\begin{gathered} 9+6+3\times12\div(-9)-216\div-9 \\ =9+6-4+24 \\ =35 \end{gathered}$

ANSWER

1) 14

2) 8

3) 35
