100 is 105 rounded to the nearest hundred hope it helped
Answer:
(4.5,-6)
Step-by-step explanation:
![2x-3y = 27\\4x+3y = 0](https://tex.z-dn.net/?f=2x-3y%20%3D%2027%5C%5C4x%2B3y%20%3D%200)
6x = 27
x = 27/6=4.5
9-3y = 27
-3y = 18
y = -6
Answer:
The polynomial that represents the area to be finished on the dulcimer shown is ![A=\frac{3}{2}h^2+h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B3%7D%7B2%7Dh%5E2%2Bh)
Step-by-step explanation:
Given:
The given figure is a trapezium with opposite parallel to each other.
The opposite parallel sides are given as:
![b_{1}=2h+1\\b_{2}=h+1](https://tex.z-dn.net/?f=b_%7B1%7D%3D2h%2B1%5C%5Cb_%7B2%7D%3Dh%2B1)
The height of the trapezoid is, ![h=h](https://tex.z-dn.net/?f=h%3Dh)
Now, the area of a trapezium is given as:
![A=\frac{1}{2}(\textrm{Sum of parallel sides)}\times (Height)\\A=\frac{1}{2}(b_{1}+b_{2})\times h\\A=\frac{h}{2}(2h+1+h+1)\\A=\frac{h}{2}(2h+h +1+1)\\A=\frac{h}{2}(3h+2)\\A=\frac{3h^2}{2}+\frac{2h}{2}\\A=\frac{3}{2}h^2+h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%28%5Ctextrm%7BSum%20of%20parallel%20sides%29%7D%5Ctimes%20%28Height%29%5C%5CA%3D%5Cfrac%7B1%7D%7B2%7D%28b_%7B1%7D%2Bb_%7B2%7D%29%5Ctimes%20h%5C%5CA%3D%5Cfrac%7Bh%7D%7B2%7D%282h%2B1%2Bh%2B1%29%5C%5CA%3D%5Cfrac%7Bh%7D%7B2%7D%282h%2Bh%20%2B1%2B1%29%5C%5CA%3D%5Cfrac%7Bh%7D%7B2%7D%283h%2B2%29%5C%5CA%3D%5Cfrac%7B3h%5E2%7D%7B2%7D%2B%5Cfrac%7B2h%7D%7B2%7D%5C%5CA%3D%5Cfrac%7B3%7D%7B2%7Dh%5E2%2Bh)
Therefore, the polynomial that represents the area to be finished on the dulcimer shown is ![A=\frac{3}{2}h^2+h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B3%7D%7B2%7Dh%5E2%2Bh)
T / 3/4 ; t = 9 3/4
9 3/4 / 3/4
9 3/4 = 39/4
39/4 / 3/4
39/4 x 4/3
39 x 4 = 156
4 x 3 = 12
156/12 / 4/4 = 39/3 = 13
No I hope this helps you!
