The absolute value parent function.
Answer:
300 centimeters
Step-by-step explanation:
1 meter is equal to 100 cm so 3 x 100 = 300
The partial circles in each corner mean that all 3 angles are identical, which means this is an equatorial triangle. In an equatorial triangle all three sides are the same.
We can set two of the equations to equal each other and solve for x:
3x -5 = 2x +20
Add 5 to each side:
3x = 2x +25
Subtract 2x from each side:
x = 25
X= 49 because the square root of 49 IS 7. :D
Good luck! :)
