<h3>
Answer: 11/20</h3>
=====================================================
Work Shown:
x = unknown horizontal length
1/5 = 0.2
Perimeter = 2*(width + length)
P = 2*(0.2 + x)
P = 0.4 + 2x
Set this equal to the given perimeter of 1 & 1/2 = 1.5 and solve for x
0.4 + 2x = 1.5
2x = 1.5-0.4
2x = 1.1
x = (1.1)/2
x = 0.55
x = 55/100
x = (5*11)/(5*20)
x = 11/20
12 + 6x + 6x + 6y = 12 + 12x + 6y
Let's see....
Let's first simplify step-by-step.
2/4 - 8z + 2(2-5)
= 1/2 + - 8z + -6
Combine Like Terms:
= 1/2 + -6
= (- 8z) + (1/2 + -6)
=(- 8z) + (1/2 + -6)
= - 8z + -11/2
___________________________________
Our answer:
= - 8z + -11/2
Hope This Helps!!!!!!!!

is the logical or/disjunction symbol.

means "

or

". Disjunction is commutative, which means

is equivalent to

.
So if

represents

and

represents

, then

means

or

.
