We have to factor the polynomial.
x^8+3x^5
Find the GCF between 1,3,x,5,8
The GCF is x^5
Divide the polynomial by x^5
x^5(x^3+3)
The little lines in each side show that the sides are the same length but you also need to find the length of the smaller side which isn’t the same. For this imagine that the shape is split into a square and a triangle and you need to find the long side of the triangle using Pythagoras
a^2 + b^2 = c^2
20^2 + 20^2 = 800
Square root of 800 = 28.3
Then do 28.3-20=8.3
So I think the answer is 20+20+20+20+20+8.3=108.3 cm
10 1/2 x 2 2/3= 28, 3 1/3 x 4 2/7= 14.2857142857, 7/2 - 4/5= 2.7

Answer:
The system of equations is
Step-by-step explanation:
Let
x ----> the number of minutes of calling time
y ----> the monthly cost of the calling plan
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
In this problem
Plan A

substitute
----> equation A
Plan B

substitute
----> equation B
therefore
The system of equations is
