You take out the squares inside of the radicals. you can do this by factoring each number. 90 is a multiple of 3x3x2x5 and 40 is 2x2x2x5. now you take out pairs. so its (3√2x5)/(2√2x5). then you cancel out the √2x5 and you're left with 3/2. :)

Answer:
14 pounds of meat
Step-by-step explanation:
Jose has 4 5/6 pounds of chicken, 3 1/3 pounds of steaks and 5 5/6 pounds of hamburgers to put on the grill. How many pounds of meat does he have for the barbecue
We have to find the sum of the the total pounds of meat.
This is calculated as:
4 5/6 pounds + 3 1/3 pounds + 5 5/6 pounds
[(4 + 3 + 5) + (5/6 + 1/3 + 5/6)] pounds
The Lowest Common Denominator
= 6
Hence:
[12 + (5 + 2 + 5 /6)] pounds
= 12 + 12/6
= 12 + 2
= 14 pounds of meat
Hence, Jose has 14 pounds of meat
Answer:
2x^3 +7x^2+3x-2
Step-by-step explanation:
3x^3 +7x^2 -x
- ( x^3 -4x +2)
------------------------
The first step is to line up the variables by degree
3x^3 +7x^2 -x
- ( x^3 -4x +2)
----------------------------
Then distribute the minus sign
3x^3 +7x^2 -x
- x^3 +4x -2
----------------------------
2x^3 +7x^2+3x-2
