6^2/2(3)+4
Follow the order of operations, (GEMDAS) which goes like this:
<em>grouping, exponents, multiplication/divison, addition/subtraction
</em>
First up is our grouping, specifically parentheses. While we do have parentheses in our expression there isn't anything going on <em>inside</em> of them that we'd have to do first. (The 2(3) is another way of writing 2×3.)
Next we have exponents, which would be our 6^2. (6 squared)
When something is squared, that means it is multiplied by itself. 6^2 = 6×6 = 36.
Now our expression is 36/2(3)+4.
Next we need to handle the multiplication and division. (order doesn't matter)
The best way to do this is from left to right. The 36/2 = 18...
Then 18(3) = 54.
If we took 36(3) then divided by 2 we would get the same answer.
However, what you <em>cannot</em> do is multiply the 2(3), simply because the 2 is a denominator of a fraction. If you don't know what this is or why, it's okay--just always do it left to right and you'll never have to worry about it.
Now our expression is 54+4.
Finally, we can handle the addition/subtraction. 54+4 leaves us with 58.
Answer: 287/8
34 4/7 and 34 9/12
Step-by-step explanation:
The other fractions are less than 1/2. 287/8 works out to 35 7/8
(x + 7)(x + 4)
(x² + 4x + 7x + 28)
x² + 11x + 28
The first thing you must do is find 10% of 2400. To do this you divide by ten (to gets the 100% to 10%). This means that 10% is 240. You now must get from 10% to 40% which means multiply by 4, so that the final answer is 960. You could also multiply 2400 by 0.4.
