Answer:
12
Step-by-step explanation:
3*4=12
the negatives cancel out.
Answer:
What the finally answer?You should use perimeter formula to answer.
Perimeter=2πr
Area(Luas)=πr²
an isosceles triangle has always two twin sides, so if one side is 3 and another is 6, there's another twin that's either 3 or 6.
now, let's take a peek at a caveat, if the twin angle missing is say 3, then the triangle has sides 3, 3 and 6, but but but, if the two slanted sides are 3 each, and the base or bottom is 6, the only way the bottom can be 6 is if the other sides lie flat on top of it, in which case we no longer have a triangle, since it'll be just 3 pancaked flat-lines, so it can't be 3, it must be 6.
The first one is the correct answer
Answer:
4x-5
Step-by-step explanation:
The area of a square is
A = s^2
16x^2 - 40x+25 = s^2
Take the square root of each side
sqrt(16x^2 - 40x+25) =sqrt( s^2)
Recognizing that the left hand side is a perfect square trinomial
sqrt((4x-5)^2) = s
4x-5 =s
The side length is 4x-5
