Answer:
Width = y + 7x
Step-by-step explanation:
Area of the rectangle = ![{y}^{2} + 8xy + 7 {x}^{2}](https://tex.z-dn.net/?f=%20%7By%7D%5E%7B2%7D%20%20%2B%208xy%20%2B%207%20%7Bx%7D%5E%7B2%7D%20)
Length of the rectangle = ![y + x](https://tex.z-dn.net/?f=y%20%2B%20x)
Lets factorise ![{y}^{2} + 8xy + 7 {x}^{2}](https://tex.z-dn.net/?f=%20%7By%7D%5E%7B2%7D%20%20%2B%208xy%20%2B%207%20%7Bx%7D%5E%7B2%7D%20)
![= > {y}^{2} + xy + 7xy + {x}^{2}](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%20%7By%7D%5E%7B2%7D%20%20%2B%20xy%20%2B%207xy%20%2B%20%20%7Bx%7D%5E%7B2%7D%20)
![= > y(y + x) + 7x(y + x)](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20y%28y%20%2B%20x%29%20%2B%207x%28y%20%2B%20x%29)
![= > (y + 7x)(y + x)](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%28y%20%2B%207x%29%28y%20%2B%20x%29)
Now ,
Width = ![\frac{Area}{Length} = \frac{(y + 7x)(y + x)}{(y + x)} = y + 7x](https://tex.z-dn.net/?f=%20%5Cfrac%7BArea%7D%7BLength%7D%20%20%3D%20%20%5Cfrac%7B%28y%20%2B%207x%29%28y%20%2B%20x%29%7D%7B%28y%20%2B%20x%29%7D%20%20%3D%20y%20%2B%207x)
Answer:
<A = ( 4 * 32 - 13 ) = 115
<C = ( x + 18 ) = 50
Step-by-step explanation:
(4x - 13 ) + 15 + ( x + 18 ) = 180 ( because the total angle of a triangle is 180)
5x + 20 = 180
5x = 160
x = 32
A. The relationship of <7 and <8 are that they are vertical angles, and are congruent.
B. Since vertical angles are congruent, you can form an equation where the two measurements equal each other.
C. 5y-29=3y+19 then plug y into your equation: 5*24-29=91
2y=48 and so: <7 = 180-91=89 (and since <8 is congruent)
y=24 <8 also equals 89
Your second problem:
complementary are two angles that add up to 90 degrees.
<B=x, <A=2x
2x+x=90
3x=90
x=30 so: <B=30 degrees, <A=60 degrees
Your third problem:
1. Since A and B are parallel, angle 3x+7 and angle 4x+5 are same-sided exterior angles. That means that they both add up to 180 degrees. So if you should add the two and make it equal 180
2. 3x+7+4x+5=180
7x+12=180
7x=168
x=24
3. <6 is a corresponding angle with angle 3x+7, meaning that they are congruent. So plug x into 3x+7: 3*24+7=79 and since <6 is congruent to 3x+7, <6=79 degrees
5000(1+.085/4)^n=1000
to find n use log:
1.02125^n
N X log1.02125
when computed=32.9
round to 33 quarters compounded
