use a calculator and work out the following and write all the figures from your work display. a) (6.2 - 3.51) x (11.7 x 0.3)

Solving the expression: we get 9.4419

Step-by-step explanation:

We need to solve the expression:

According to DMAS rules first we solve brackets and then we will multiply the results found after solving brackets

So,

First we solved the terms (6.2-3.51) and get 2.69 and by solving (11.7 x 0.3) we get 3.51

Now, we will multiply 2.69 with 3.51 to get the final result.

The final result is 9.4419

So, solving the expression: we get 9.4419

225x²+4=0
