Answer:
36+64=100 100 to the square root is 10
Step-by-step explanation:
I'm not giving a diagram just draw a triangle and make the base of it 8 and the length of it 6 but the diagonal part 10
It's the pythagorean theorum. a^2 + b^2 = c^2
^2= to the 2nd power. or squared.
In this case it really doesnt matter which one you label for this part of math.
so 8^2 + 6^2 = C^2 where C is the shortest distance between the houses.
and 8 and 6 were the lengths given.
64+36=100
100's square root is 10 because 10^2 is 100 or 10*10 is 100. If you dont know what squaring is.
Its multiplying something by that something once so 1 squared is 1 because its 1*1 you are multiplying it once 2 squared or 2^2 is 4 because 2*2 is 4 3 squared or 3^2 is 9 because 3*3 is 9. 4 squared is 16 because 4*4 is 16. and if you did 2 to the power of 3 of 2 cubed it would be 8 because 2*2*2 is 8.
Tangency is when a line is fully outside the circle and touches it in one place.
The point of tangency would be point H

Answer: C 2:3
Step-by-step explanation:
total students = 25
total girls = 15
total boys = 25-15 = 10
boys:girls = 10:15
divide by 5 to get 2:3
Answer:
x = 2 x = -6
Step-by-step explanation:
2 (x+2) ^2-4=28
Add 4 to each side
2 (x+2) ^2-4+4=28+4
2 (x+2) ^2= 32
Divide by 2
2/2 (x+2) ^2=32/2
(x+2)^2 = 16
Take the square root of each side
sqrt((x+2)^2) =±sqrt( 16)
x+2 = ±4
Subtract 2 from each side
x+2-2 = -2±4
x = -2±4
x = -2+4 and x = -2-4
x = 2 x = -6
