The little lines on each side of the rhombus mean that all the sides are the same length.
We can set line LM and MN equal to solve for X, then we can solve the length of a side.
3x-3 = x+7
Add 3 to each side:
3x = x +10
Subtract x from each side:
2x = 10
Divide both sides by 2:
x = 10/2
x = 5
Now we have the value for x, replace x in one of the side formulas:
x +7 = 5+7 = 12
Each side = 12 units.
The perimeter would be 12 + 12 + 12 + 12 = 48 units.
Answer:
x=-1
Step-by-step explanation:
54x+64=49x+59
subtract 64
54x=49x-5
subtract 49x
5x=-5
divide by 5
x=-1
Answer:
Step-by-step explanation:
4 triangles
Each of the 3 from the vertical ones has area
A = bh/2 = 10.12/2 = 60ft^2
The latter surface pointing down
A = bh/2 = 10.8.7/2 = 43.5 ft^2
SO summation of all
60+43.5 = 103.5 ft^2
The answer is 28.2 (or about 28). to find this, you do 23,572 / 837.
