Answer: 4a+6b=ab
Step-by-step explanation:
A polygon doesn't have to have any pairs of congruent sides. You'd need to further define the type of polygon before you could answer this.
Answer:
90 - 54w
Distribute 18 to both numbers.
Answer:
![x^{2} - 4](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-%204)
Step-by-step explanation:
in this case,
is your number. we will always note square with the tiny two at the top of the number.
Four less than anything is easily shown with a minus four.
eg. four less of 12 square:
= :)
The final equation of line that passes through (9, 0) AND (0, -6) is:
![y=\frac{2}{3}x-6](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7Dx-6)
Further explanation:
The general form of equation of line is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Given
(x1,y1) = (9,0)
(x2,y2) = (0, -6)
We have to find the slope first:
![m=\frac{y_2-y_1}{x_2-x_1}\\= \frac{-6-0}{0-9}\\=\frac{-6}{-9}\\=\frac{2}{3}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5C%3D%20%5Cfrac%7B-6-0%7D%7B0-9%7D%5C%5C%3D%5Cfrac%7B-6%7D%7B-9%7D%5C%5C%3D%5Cfrac%7B2%7D%7B3%7D)
Putting the value of slope in general form
![y=\frac{2}{3}x+b](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7Dx%2Bb)
To find the value of b, we have to put a point in the equation
Putting (9,0) in equation
![0=\frac{2}{3}(9)+b\\0=2*3+b\\0=6+b\\b=-6](https://tex.z-dn.net/?f=0%3D%5Cfrac%7B2%7D%7B3%7D%289%29%2Bb%5C%5C0%3D2%2A3%2Bb%5C%5C0%3D6%2Bb%5C%5Cb%3D-6)
Putting the values of b and m in general form
The final equation of line that passes through (9, 0) AND (0, -6) is:
![y=\frac{2}{3}x-6](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7Dx-6)
