Answer:
Its the second choice.
Step-by-step explanation:
Substitute x = 2 into the function .
If you mean 2x=40 x=20
but if you mean x^2=40 i think its x=80
1 1/9 + 3 5/8 is 4 53/72.
My reason is you must equalize 1 1/9 to 1 8/72.
Then equalize 3 5/8 to 3 45/72.
Now add them together and do not add the denominators. Add the numerators, and the whole numbers. Simplifying is unnecessary. The answer should be <u>4 53/72</u>.
Answer:The area method, also sometimes called the box method, is an alternative to the standard algorithmic method (see below) for long multiplication.The standard algorithm is generally a faster method but, unlike the area method, it does not promote understanding or encourage the development of mathematical thinking.please mark as brainliest
