Since you're trying to find the side lenghts of a square, all we need to do is square root the area. So, the square root of 4 (the area) is 2.
So, all of the sides of the square are 2 meters long.
Answer:
The value of y is 
Step-by-step explanation:
we have
-----> equation A
-----> equation B
To eliminate the x-variable and find the value of y Multiply the equation A by -18/4 both sides or multiply the equation B by -4/18 both sides
I choice
Multiply the equation A by -18/4 both sides
![(-18/4)[4x+3y]=6*(-18/4)](https://tex.z-dn.net/?f=%28-18%2F4%29%5B4x%2B3y%5D%3D6%2A%28-18%2F4%29)
------> equation C
Adds equation B and equation C
34.5=4h+7c
(34.5-7c)/4=h
Put h= (34.5-7c)/4 into another equation
30.5=8h+3c
30.5=2(34.5-7c)+3c
30.5=69-14c+3c
11c=38.5
c=38.5/11
Put c=38.5/11 into one of the equations
to calculate the h.
The first one is -5,-3 ab.
Answer:
y = 1/2x + 1
Step-by-step explanation:
find the slope and since it is perpendicular the slope is the opposite reciprocal so it would be 1/2
y = 1/2 x + b and then plug in the coordinate to the equation
3 = 1/2(4) + b
b = 1 and then plug everything back into the equation
y = 1/2x + 1
