5/16
You have to simplify both sides of the equation, then isolating the variable.
Answer:
In order to solve this problem, you have to find the lowest common denominator. Take multiples of both 6 and 4 and see which is the lowest you have in common.
4: 4, 8, 12, 16, 20
6: 6, 12, 18, 24
So 12 is the lowest common multiple....
5/6 x ?/? = ?/12 (you have to multiply the numerator and the denominator by the same number)
3/4 x ?/? = ?/12 (you have to multiply the numerator and the denominator by the same number)
When the denominators are the same, you can subtract the numerators. The denominator will stay 12!
Step-by-step explanation:
YAY! I want a brain
Perimeter :
because there are four sides to a square and all sides are the same, the answer is 4(2x-9)
area:
area is basically length times width so the answer is (2x-9)(2x-9) or (2x-9)^2
2 because it is the only degree there in the problem
