Answer:
y = 50
Step-by-step explanation:
All triangle angles add up to 180 degrees.
To set this equation up, you need to add everything given in the triangle and set it equal to 180:
y + y + 80 = 180
<em><u>Add like terms:</u></em>
2y + 80 = 180
<u><em>Subtract 80 from both sides:</em></u>
2y + 80 = 180
- 80 - 80
___________
2y = 100
<u><em>Divide both sides by 2:</em></u>
y = 50
<u><em>If you're unsure, you can plug in the 50 for y:</em></u>
y + y + 80 = 180
50 + 50 + 80 = 180
100 + 80 = 180
180 = 180
Step-by-step explanation:
See attached picture.
First, compare the highest term of the dividend (x²) to the highest term of the divisor (x). We need to multiply the divisor by x.
When we do that, we get x² + 5x. Subtracting this from the dividend, we get -9x + 11.
Now repeat the process. Compare the highest term of the new dividend (-9x) to the highest term of the divisor (x). We need to multiply by -9.
When we do that, we get -9x − 45. When we subtract from the new dividend, we get 56.
So the quotient is x − 9, and the remainder is 56.
Ena is -1.39 meters tall
54 centimeters = 0.01 meters
0.01 meters - 1.4 meters = - 1.39 meters
Answer:
The area of the rectangle in terms of 'x' = 13x
Step-by-step explanation:
Using the perimeter formula to find the width w.
![P=2(l+w)](https://tex.z-dn.net/?f=P%3D2%28l%2Bw%29)
![P = 2l + 2w](https://tex.z-dn.net/?f=P%20%3D%202l%20%2B%202w)
![2w = P-2l](https://tex.z-dn.net/?f=2w%20%3D%20P-2l)
Dividing both sides by 2
![w\:=\:\frac{P}{2}-2](https://tex.z-dn.net/?f=w%5C%3A%3D%5C%3A%5Cfrac%7BP%7D%7B2%7D-2)
as P = 30 cm
![w\:=\:\frac{30}{2}-2](https://tex.z-dn.net/?f=w%5C%3A%3D%5C%3A%5Cfrac%7B30%7D%7B2%7D-2)
![w\:=\:15-2](https://tex.z-dn.net/?f=w%5C%3A%3D%5C%3A15-2)
cm
Using the formula of the rectangle area
![A = wl](https://tex.z-dn.net/?f=A%20%3D%20wl)
substitute w = 13 and l = x in the formula
![A=13\times \:x](https://tex.z-dn.net/?f=A%3D13%5Ctimes%20%5C%3Ax)
![A = 13x](https://tex.z-dn.net/?f=A%20%3D%2013x)
Therefore, the area of the rectangle in terms of 'x' = 13x
