To find the area you multiply l x w so, to find the sides you do the opposite, sq root of 24,200 (we can use the square root because we know it is a square and all sides are equal)=155.563492. This is only the length of one side. 155.563492*4=622.253968 which is a rational number.
The perimeter is a rational number.
Answer:
<em>x = 3 and y = 0</em>
Step-by-step explanation:
3y+x=3
-2y+5x=15
Isolate y in 3y + x = 3 :
Substitute 
in -2y + 5x = 15 :
Simplify the equation :
Isolate x in 
:
Proving x = 3
Isolate y in 
:
Proving y = 0
Your solved system of equations are x being 3, and y being 0.
Answer: your answer is going to be 1/7
Step-by-step explanation:
Answer:
A = 177.46
Step-by-step explanation:
A = 6*6+6root((6/2)^2+11.4^2)+6root((6/2)^2+11.4^2)
A = 177.46
Answer: A
Step-by-step explanation:
To find the inner product of two vectors (a,b) and (c,d) you would use the equation (a * c) + (b * d)
So for (7,2) and (0,-2) the inner product would be
(7 * 0) + (2 * -2)
= 4
The vectors are only perpendicular when the inner product is equal to 0. Since it is equal to -4 in this case, the vectors are not perpendicular.
A -4; no
