Answer:
I think the answer is 32<em>cm²</em>
Step-by-step explanation:
A lot of mathematics using a calculator and checking all possible answers led me to this possible solution.
Let's denote Cindy's age which is unknown with X
We know that Cindy's age is 3 times her age 6 years ago.
6 years ago Cindy's age was the present age (X) - 6 : X-6
The fact that the present age is 3 times her age 6 year ago can be written as:
3*(X-6)
So, finally:
X=3*(X-6)
40x - 2 because you combine like terms so it's 40x and then combine 8 and -10
Answer:
x=10
Step-by-step explanation:
Set up the equation, (3x+6)+54=90 because both angles equal up to 90 degrees, and then solve for x.
First you need to pick a number for y. Lets say you pick 0
Then you need to +3 to each side
Then you can say 3=x+2 or -3=x+2.
To find x you need to subtract 2.
You answer would be (1,3) and (-5.-3)
