The simple way of calculating a perimeter is to add all of the sides.
For a rectangle this would equal 2 x length + 2 x width
P = 2(6x + 3) + 2(-2x - 5)
= 12x + 6 - 4x - 10
= 8x - 4
At a higher level both the length and width must be greater than zero (= zero is a trivial rectangle)
6x + 3 > 0
6x > -3
x > -0.5
-2x - 5 > 0
2x + 5 < 0 (multiplying by -1 reverses the inequality)
2x < -5
x < -2.5
This rectangle cannot exist as x cannot be < -2.5 and > -0.5 at the same time!

I'm assuming you mean triangle angles?
If so, all angles add up to 180 so combine them and set them equal to 180.
51+82+5x+2=180
135+5x=180
5x=45
x=9
Answer:
A : debit to Service Charge Expense of $18.
Step-by-step explanation:
First, one should calculate the value, in dollars of the credit card service fee
Fee = 2% x $900 = $18.
Since this fee is classified as "money coming out" of the account, the entry to a record of this transaction should include a debit to Service Charge Expense of $18.
The correct answer is alternative A.
*The whole purchase amount ($900) should be credited and the service expense should be debited, unlike alternative C, which merges both entries into one.
Answer:
24
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
x/2 = 3
x = 3×2
x = 6
Therefore
4x = 4 × 6
4x = 24
