Given Fig.is a triangle
Perimeter is simply sum of the all sides of a triangle
1/3x + 7/x^2 + (x+2)/x
=[ x+ 21 + 3x(x+2)]/3x^2
= (x+ 21 + 3x^2 + 6x)/3x^2
= (3x^2 + 7x +21)/3x^2
Answer: 6 x 6 is 6 squared (6^2)
Explanation:
Any number multiplied by itself is squared. (ie. 36 x 36 is 36 ^ 2, 2 x 2 is 2^2 etc)
Hope this helps!! :)
2(2)+3y=13
4+3y=13
3y=9
y=3
The answer is B
D and E. An acute angle is any angle that is less than 90(a right angle). A is an obtuse angle(more than 90). And B + C are right angles. Hope this helps you!
