Answer:
C. ![\frac{3x+4}{x^2}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%2B4%7D%7Bx%5E2%7D)
Step-by-step explanation:
The given expression is;
![\frac{3}{x}+\frac{4}{x^2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx%7D%2B%5Cfrac%7B4%7D%7Bx%5E2%7D)
The Least Common Denomnator (LCD) is ![x^2](https://tex.z-dn.net/?f=x%5E2)
We collect LCD to get;
![\frac{3x+4}{x^2}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%2B4%7D%7Bx%5E2%7D)
The correct choice is C
Answer:
![m\angle a=48^o\\m\angle b=82^o\\m\angle c=50^o](https://tex.z-dn.net/?f=m%5Cangle%20a%3D48%5Eo%5C%5Cm%5Cangle%20b%3D82%5Eo%5C%5Cm%5Cangle%20c%3D50%5Eo)
Step-by-step explanation:
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
![m\angle a+m\angle b+m\angle c=180^o](https://tex.z-dn.net/?f=m%5Cangle%20a%2Bm%5Cangle%20b%2Bm%5Cangle%20c%3D180%5Eo)
substitute the given values
![4x^o+(7x-2)^o+(5x-10)^o=180^o](https://tex.z-dn.net/?f=4x%5Eo%2B%287x-2%29%5Eo%2B%285x-10%29%5Eo%3D180%5Eo)
solve for x
![(16x-12)^o=180^o](https://tex.z-dn.net/?f=%2816x-12%29%5Eo%3D180%5Eo)
![16x=180+12\\16x=192\\x=12](https://tex.z-dn.net/?f=16x%3D180%2B12%5C%5C16x%3D192%5C%5Cx%3D12)
Find the angle measurements
![m\angle a=4(12)=48^o](https://tex.z-dn.net/?f=m%5Cangle%20a%3D4%2812%29%3D48%5Eo)
![m\angle b=7(12)-2=82^o](https://tex.z-dn.net/?f=m%5Cangle%20b%3D7%2812%29-2%3D82%5Eo)
![m\angle c=5(12)-10)=50^o](https://tex.z-dn.net/?f=m%5Cangle%20c%3D5%2812%29-10%29%3D50%5Eo)
You could also say something such as 10 + (-3) or |-10+3|.

Answer:
270
Step-by-step explanation:
✔️Area of the Patio = bh
b = 12 ft = 144 in.
h = 10 ft = 120 in.
Area of Patio = 144*120 = 17,280 in.²
✔️Area of Brick Paver = bh
b = 8 in
h = 8 in
Area of the Brick Paver = 8*8 = 64 in.²
The number of quaver needed to cover the Patio = area of Patio ÷ area of one brick quaver
= 17,280/64 = 270
