Hi there! The answer is 10.

We can use PEMDAS (Parenthesis, exponents, multiply, divide, add, subtract) to find our answer.
Since we cannot work inside the parenthesis in this question and since we don't have exponents, we can move on to multiplying.

Our next step would be subtracting. To make the process of subtracting some easier, I'll first change the fraction into a decimal.

Finally subtract.

The answer is 10.
~ Hope this helps you!
The area is 336 is you multiply the outer numbers then subtract the numbers on the in side that's what you get
Answer:
-150
Step-by-step explanation:
x^2 - 7x^2 - 18x +42
3^2 - 7(3)^2 - 18(3) + 42
9 - 63 - 54 + 42
-54 -54 + 42
-108 + 42
-150
