Answer:
3sqrt2
Step-by-step explanation:
If a side length is a, then a^2 + a^2 = 36
2a^2 = 36
a^2 = 18
a = 3sqrt2
Or, you can remember that in a square, if you cut it in half diagonally, you get a 45-45-90 triangle, so the sidenglth is diagonal/sqrt2
Answer:
-17
Step-by-step explanation:
Answer:
11.66
Step-by-step explanation:
c² = a² + b²
c²= 6² + 10²
c²= 136
c= √136
c= 11.66 ( to two decimals)
Answer:
y= -1 and x = 10
Step-by-step explanation:
(1) x+3y=7
(2) 2x-4y=24
Clear x from the 1st equation: x=7-3y
And replace x from the 2do one: 2(7-3y)-4y=24
14-6y-4y=24
-6y-4y=24-14
-10y=10
y=-10/10
y=-1
Now we have y=-1, let's finde x:
x=7-3y
x=7-3(-1)
x=7+3
x=10
Yes it is and 8% increase
