Answer:
Each person paid $24.
Step-by-step explanation:
1. Find 20% of 40. Since 20% is equal to 1/5, we can divide 40 by 5 to get 8. Together they tipped $8.
2. We know that the total amount they paid was $48, so we divide that in half to get the answer. 48 divided by 2 is 24.
5 because -2+5=3 explanation
Answer
The answer is negative 14.
Step-by-step explanation:
When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.
The value of the expression
is ![2xy\sqrt{y} + 2xy^2\sqrt{x}](https://tex.z-dn.net/?f=2xy%5Csqrt%7By%7D%20%2B%202xy%5E2%5Csqrt%7Bx%7D)
<h3>How to evaluate the sum?</h3>
The attachment represents the proper format of the question
The summation expression is given as:
![\sqrt{x^2y^3} + 2\sqrt{x^3y^4} + xy\sqrt y](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E2y%5E3%7D%20%2B%202%5Csqrt%7Bx%5E3y%5E4%7D%20%2B%20xy%5Csqrt%20y)
Expand the radicands
![\sqrt{x^2y^2 * y} + 2\sqrt{x^2y^4* x} + xy\sqrt y](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E2y%5E2%20%2A%20y%7D%20%2B%202%5Csqrt%7Bx%5E2y%5E4%2A%20x%7D%20%2B%20xy%5Csqrt%20y)
Evaluate the square roots
![xy\sqrt{y} + 2xy^2\sqrt{x} + xy\sqrt y](https://tex.z-dn.net/?f=xy%5Csqrt%7By%7D%20%2B%202xy%5E2%5Csqrt%7Bx%7D%20%2B%20xy%5Csqrt%20y)
Add the like terms
![2xy\sqrt{y} + 2xy^2\sqrt{x}](https://tex.z-dn.net/?f=2xy%5Csqrt%7By%7D%20%2B%202xy%5E2%5Csqrt%7Bx%7D)
Hence, the value of the expression
is ![2xy\sqrt{y} + 2xy^2\sqrt{x}](https://tex.z-dn.net/?f=2xy%5Csqrt%7By%7D%20%2B%202xy%5E2%5Csqrt%7Bx%7D)

Answer:
(x-2) and (10x+7)
Step-by-step explanation:
10x²-13x-14
10x²-20x+7x-14
10x(x-2)+7(x-2)
(x-2)(10x+7)
the factors are (x-2)(10x+7)
meaning that the length and breadth are (x-2) and (10x+7)
