Let's solve this problem step by step.

1. First of all we have this equation:

3(x + 4y) + 5(2x - y)

2. Let's apply distributive property:

3x+12y + 10x - 5y

3. Let's order this expression according to the variables:

3x + 10x + 12y-5y

4. Let's sum equal terms:

13x + 7y

Suppose two adjacent endpoint of a rotated square are located at (-4, -6) and (5, -1) on the coordinates axes. What is the lengt
Rufina [12.5K]
To find the length of the side of the square, we just need to find the distance between the two endpoints. This problem can quickly be solved by using the distance formula, but for those who are not familiar with it, we can simply solve it by analyzing a triangle.

Take a look at the diagram below. We are interested in x. To find this we have created a right triangle. The horizontal component is just the distance between the x coordinates of the two points while the vertical component is the distance between the y coordinates.

The horizontal component is 9 and the vertical component is 5. We can now get x by using the pythagorean theorem:

x^{2}= 9^{2} + 5^{2} =81+25=106
x= \sqrt{106} which is approximately equal to 10.30 units.

ANSWER: 
The length of the side of the square measures 10.30 units.

Natasha_Volkova [10]
Divide total cups he drank by the # of cups in each bottle.

7 ÷ 3= 2.3333

Since each bottle only holds 3 cups, he drank 3 bottles of water. He didn't drink all the water in the third bottle, but he started drinking the third bottle.

ANSWER: 3 bottles

Hope this helps! :)
