It’s already a fraction so it cannot be simplified anymore
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!
Answer:
5
Step-by-step explanation:
( divide numerator and denominator by 5 ) , then

( with missing number ? = 5 )
Answer:
A = 18cm²
Step-by-step explanation:
Answer:
x = 60
Step-by-step explanation:
That square on the angle means 90 degrees so since the other angle is 30 that means x has to be 60
