ANSWER
![15 {x}^{2} + 22x - 5](https://tex.z-dn.net/?f=15%20%7Bx%7D%5E%7B2%7D%20%2B%2022x%20-%205)
EXPLANATION
It was given that, the length of the rectangular building is
![(3x + 5) \: meters](https://tex.z-dn.net/?f=%283x%20%2B%205%29%20%5C%3A%20meters)
and the width of the is
![(5x - 1) \: meters](https://tex.z-dn.net/?f=%285x%20-%201%29%20%5C%3A%20meters)
The area of a rectangular building is calculated using the formula for finding the area of a rectangle.
![A = l \times w](https://tex.z-dn.net/?f=A%20%3D%20l%20%5Ctimes%20w)
Since the dimensions are given in terms of x, the area is also a function of x,
![A(x) = (3x +5 )(5x - 1)](https://tex.z-dn.net/?f=A%28x%29%20%3D%20%283x%20%2B5%20%29%285x%20-%201%29)
We expand to get,
![A(x) = 3x(5x - 1) + 5(5x - 1)](https://tex.z-dn.net/?f=A%28x%29%20%3D%203x%285x%20-%201%29%20%2B%205%285x%20-%201%29)
![A(x) = 15 {x}^{2} - 3x + 25x - 5](https://tex.z-dn.net/?f=A%28x%29%20%3D%2015%20%7Bx%7D%5E%7B2%7D%20%20-%203x%20%2B%2025x%20-%205)
![A(x) = 15 {x}^{2} + 22x - 5](https://tex.z-dn.net/?f=A%28x%29%20%3D%2015%20%7Bx%7D%5E%7B2%7D%20%2B%2022x%20-%205)

Answer:
4. 3 units
5. Triangle
6. (0,2)
Step-by-step explanation:
4. The distance between the x axis and the point (8,3) is 3 units
5. Triangle will be formed if the points A(-3, 0), B (0,3) and C (3,0) are joined together
6. Since the point lie on the y-axis, its x co-ordinate will be zero and the point will be (0,2)
Answer:
300 lbs
Step-by-step explanation:
We know that Larry bench pressed 200 lbs last week, and that he is supposed to increase by 15%. We know that any number times one is that same numbers. That means a number that is increaseing has to be greater than 1. So, we have to convert 15% into a decimal. That is 0.15. That plus one is 1.15. Now we just have to multiply 1.15 with 200. We get 300.
Ok, so after you do -8a+5a, you also have to do 6 -35, getting the equation
-29-3a
