Answer:
4(m+4)
Step-by-step explanation:
4m+16
Rewriting
4*m + 4*4
Factor out 4
4(m+4)
1)
8² + 15² = 17²
64 + 225 = 289
This is true, so the triangle is a right triangle.
2)
4² + 12² = 13²
16 + 144 = 169
This is false, so the triangle is not a right triangle.
3)
20² + 21² = 27²
400 + 441 = 729
This is false, so the triangle is not a right triangle.
4)
28² + 45² = 53²
784 + 2,025 = 2,809
This is true, so the triangle is a right triangle.
F* you B*!!!!!! Your so S*! That's the easiest thing in the world!!
.675 square units is the answer
I assume the equation is supposed to be

Then we can write

Take the logarithm of base 3/8 on both sides:



- - -
If the equation is actually
, I'm afraid it cannot be solved exactly.
