Total- 2,100 m
Pool- 1,250 m
Deck- 2,100-1,250= The area of the deck will be 850 m
You should get constants to one side, and variables to the other. Like this:
4+4x=4x+7
Subtract 4x from left side: 4=4x+7-4x
Combine 4x, that would give you 0: 4=7
But... that isn't possible? I'm not completely sure, is the question just asking you to simplify?
Difference between the area of the triangle and square is 25
Step-by-step explanation:
- Step 1: Find the area of the triangle given its 3 sides using the Heron's formula.
Area of the triangle = where s =
⇒ s = (6 + 8 + 10)/2 = 24/2 = 12
=
= = = 24 sq. units
- Step 2: Find the area of the square with perimeter = 28 units.
Perimeter of the square = 4 × side = 28
⇒ Side of the square = 28/4 = 7 units
⇒ Area of the square = (side)² = 7² = 49 sq. units
- Step 3: Find the difference between the area of the square and triangle.
Difference = 49 - 24 = 25
I would say B, one because on A it is not NEARLY it IS, and second it is true, lol.
