Answer: 9 and 21
Step-by-step explanation:
board=30m
divide by 2 pieces
one piece, we call it a
b, the other piece is b= 2a+3
a+b=30
a+2a+3=30
3a=30-3
3a=27
a=9
b=21
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.
Answer:
Step-by-step explanation:
What is the length of the apothem, rounded to the nearest inch? recall that in a regular hexagon, the length of the radius is equal to the length of each side of the hexagon. 4 in. 5 in. 9 in. 11 in.
First equation: x=-y+8
Second equation: on the picture
I believe it would be 160000
