Question

Simplify the following expression.

Answer 1

Step-by-step explanation:      

Step 1: Add the numbers: 9.5 +6.2 = 15.7

$=8.6\left(15.7-3.5^2\right)$

$3.5^2=12.25$

$=8.6\left(15.7-12.25\right)$

Step 2: Subtract the numbers: 15.7 - 12.25 = 3.45

$= 3.45X 8.6$

Step 3: Multiply the numbers: 8.6 × 3.45 = 29.67

$=29.67$

- To solve this equation, the first step is to add the numbers 9.5 + 6.2 into the equation and it will lead to 15.7 as the number for step one.

- To solve this equation, the second step is to subtract the numbers 15.7 - 12.25 into the equation and it will lead to 3.45 as the answer.

- To solve this equation, the third step is to multiply the numbers 8.6 x 3.45 into the equation and it will lead 29.67 as the final answer for the whole equation.

Answer:      

$=29.67$
