Answer:
- 12.4
Step-by-step explanation:
Substitute the given values into the expression
- | 5(- 2) + (- 3) | + | 3(3) + 2(- 4.2) |
= - | - 10 - 3 | + | 9 - 8.4 |
= - | - 13 | + | 0.6 |
= - | 13 | + | 0.6 |
= - 13 + 0.6
= - 12.4
Knowing the squareroot of 81 is 9, we can easily know that square root of 83 is close to 9.
9 to the closest tenth is 10.
