Answer:Commutative property of addition
Step-by-step explanation: It’s because you’re adding stuff
See the solution in the pdf file attached. Please, let me know if it is satisfactory for you.
Perimeter of rectangle:
P = 2(L + W)
P = 250 (given)
L = 3W - 35 (given)
250 = 2(3W -35 + W) ↔ 125 = 4W - 35
4W = 125 +35 =160 And W = 40 ft
And L = 3x40 - 35 = 85 ft
Answer:
C)No Solution
Step-by-step explanation:
Given 2 equations
Mentioned to solve using eliminations method
4x-2y=1
2x-y=2
Multiply second equation with 2
⇒second equation is 4x-2y=4
Now subtract second equation from 1st equation
4x-2y-(4x-2y)=1-4
4x-4x-2y+2y=-3
0+0=3
0=3
But 0≠3
Therefore there exists no solutions for the given pair of equations
Both equations are Parallel lines as they have the same slope
(x+1)(x-2) = x(x-2) + 1(x-2)
= x.x - x . 2 + 1. x - 1 . 2
= x² - 2x + x -2
= x²-x -2
