Answer:
ee
Step-by-step explanation:
e
So given l = x+5 and w = x
area represented by equation x^2 +5x = 300
x^2 +5x -300 =0
(x+20)(x-15)=0
x+20 =0
x = -20
x-15=0
x=15
so from these result the width of rectangle equal 15 inches and the length of rectangle equal 20 inches
Answer:Since -2 can not equal 0, there is no solution. The lines are parallel. It is an inconsistent system.
Step-by-step explanation:
The first step in solving a system of equations by substitution is solving one of the equations for one of the variables
x - y = 0 Equation 1
x - y + y = 0 +y Add y to each side
x = y Simplify
After solving an equation for one of the variables, substitute that value into the other equation. In this problem, I can substitute y for x.
x - y - 2 = 0 Equation 2
y - y - 2 = 0 Substitute the value of x from equation 1
0 - 2 = 0 Inverse Property of addition
-2 = 0 Identity Property of addition
57-34x5-45-67x78x98 equals fifty nine
