Step-by-step explanation:
Answer:
a = x² + 3x - 40
Step-by-step explanation:
a = l * w
a = (x - 5)(x + 8)
a = x(x + 8) - 5(x + 8)
a = (x² + 8x) + (- 5x - 40)
a = x² + 3x - 40
The easiest way to determine the answer is to just divide $57/$60 = 0.95 or 95%
This can be solved using permutations.You can get more into this online or just accept a quick answer here.
Since there are certain roles to be filled this is a permutation.
You need a somewhat smart calculator for this.
If I remember this right you'd type in the number of people you are choosing from, P , and then the places you are trying to fill.
So it should look like this:
13 P 5
You can find where permutations and combinations are in your calculator using a handbook or the internet but usually it looks like nPr for permutation or nCr for combination.
Answer:
13t^2 +17
Step-by-step explanation:
It helps to regroup the terms so like terms are together. Then you can more easily see how to combine them.
(7t^2 +9) + (6t^2 +8) = 7t^2 + 9 + 6t^2 + 8
= 7t^2 + 6t^2 + 9 + 8
= t^2·(7 + 6) + (9 +8)
= 13t^2 +17
