The answer would be 4.12 because the other one is a negative
we are given trapezoid
Area is 104cm^2
a=4x-1 cm
b=x+2 cm
h=8cm
we can use area formula
![Area=\frac{1}{2} (a+b)*h](https://tex.z-dn.net/?f=%20Area%3D%5Cfrac%7B1%7D%7B2%7D%20%28a%2Bb%29%2Ah%20)
we can plug above values
![104=\frac{1}{2} (4x-1+x+2)*8](https://tex.z-dn.net/?f=%20104%3D%5Cfrac%7B1%7D%7B2%7D%20%284x-1%2Bx%2B2%29%2A8%20)
now, we can solve for x
![104=\frac{1}{2} (5x+1)*8](https://tex.z-dn.net/?f=%20104%3D%5Cfrac%7B1%7D%7B2%7D%20%285x%2B1%29%2A8%20)
![13=\frac{1}{2} (5x+1)](https://tex.z-dn.net/?f=%2013%3D%5Cfrac%7B1%7D%7B2%7D%20%285x%2B1%29%20)
![26= (5x+1)](https://tex.z-dn.net/?f=%2026%3D%20%285x%2B1%29%20)
![5x=25](https://tex.z-dn.net/?f=%205x%3D25%20)
so, we get
![x=5](https://tex.z-dn.net/?f=%20x%3D5%20)
length of longer base is a
we can plug x=5 into a
![a=4*5-1](https://tex.z-dn.net/?f=%20a%3D4%2A5-1%20)

Considering the given graph, the number of solutions for the system of equations is given by:
b.) one
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In a graph, the number of solutions is given by the number of times the lines intersect. Hence, in this problem, the system has one solution, and option b is correct.

Answer:
y = 5x - 4
Step-by-step explanation:
Step 1: Write known variables
m = 5
y = 5x + b
Step 2: Find <em>b</em>
6 = 5(2) + b
6 = 10 + b
b = -4
Step 3: Rewrite equation
y = 5x - 4
200.
Explanation:
20% of 100 is 20.
Or 20/100.
We can find the equivalent fraction to get to 40 as the numerator.
To get an equivalent fraction, we must multiply both numbers by the same amount
20 x 2 is 40
—
100 x 2 is 200
40/200 = 20%
Hope this helps!
