The value of the expression is84.2.

Step-by-step solution

Step 1  . Order of operations

To evaluate any expression involving more than one operation, follow the below order of operations:

• First evaluate expressions inside grouping symbols like parentheses ( ) or brackets [ ].
• Evaluate the exponents.
• Perform Multiplication and division from left to right.
• Perform addition and subtraction from left to right.

Step 2  . Multiply from left to right

To evaluate the expression$70.2+4\left(3.5\right)$, first remove the parenthesis and multiply the numbers as shown below,

$\begin{array}{c}70.2+4\left(3.5\right)=70.2+4\cdot 3.5\\ =70.2+14\end{array}$

Step 3  . Add the numbers

Now to simplify further, add the numbers to get

$\begin{array}{c}70.2+4\left(3.5\right)=70.2+14\\ =84.2\end{array}$

Thus, the value of the expression is 84.2.
