I believe the correct option is C after I checked it over and over again...
Answer:
3(sqrt42) ft
Step-by-step explanation:
If <em>l</em> is side length of square patio, then area of patio would be <em>l^2.</em>
<em>l^2 = 378</em>
<em>l = sqrt378 = 3(sqrt42)</em>
Answer:
Step-by-step explanation:
Let one of the side = x
So, other side = x - 2
Area = 360 sq.m
x*(x - 2) = 360
x*x - x * 2 = 360
x² - 2x -360 = 0
x² + 18x - 20x - 18*20 = 0
x(x +18) - 20*(x + 18 ) = 0
(x + 18)(x -20) = 0
{x + 18 is ignored as measurement will not be a negative number}
x - 20 = 0
x = 20
Length of the longer side = 20 m
The answer is 39
52-4*6+11=39
I hope this helps.
Answer:
Step-by-step explanation:
4.coordinate points are:
(-2,3)=(x1 , y1)
(1,y)=(x2 , y2)
slope =y2-y1/x2-x1
2=y-3/1-(-2)
2=y-3/1+2
2=y-3/3
do cross multiplication
2*3=y-3
6+3=y
9=y
3 no.
3(1-x)=-2(x-1)
3-3x=-2x+2
3-2=-2x+3x
1=x
4+y/3=2
4+y=3*2
4+y=6
y=6-4
y=2
