Answer:
The third side is 17m-4
Step-by-step explanation:
The perimeter of a triangle is the sum of the three sides. Call the third side x
x + 5m-7 + 2m+5 = 24m -6
Combine like terms
x +7m-2 = 24m -6
Solve for x
Subtract 7m from each side
x +7m-7m -2 = 24m-7m -6
x -2 = 17m-6
Add 2 to each side
x-2+2 = 17m-6+2
x = 17m-4
The third side is 17m-4
Answer:
B
Step-by-step explanation:
Every number has factors. Some numbers share factors. To
simplify a fraction, divide the numerator and the denominator,
each separately, by the factors they share
in common. The only common factor, at the end, should be 1.
Here's an example:
I first divided by 9 and ten by x.
Answer:
$23.27
Step-by-step explanation:
yes
All angles are 90 degrees, which cancels out a kite and a rhombus, leaving you with two options (rectangle or square). Using Pythagoras' theorem, you can work out that all sides are also of equal length, which means this shape is a square :)
