Answer:
The formula for calculating the circumference of a circle is 2*pi*r. Because pi does not have an end, we'll use 3.14, since that is the approximate value of pi.
2*6*3.14 = 37.68
The outer rim of the pool is about 37.68 meters long
Step-by-step explanation:
It’s probably 40 because it says about how long not exactly.

2x-y =3
multiply by 4
8x - 4y = 12
3x +4y = 10 (unchanged equation)
------------------add
11x = 22
answer is A. the first.
first equation multiplied by 4 then sum to get 11x = 22
Answer:
f^-1(x) = ( x + 6 )/4
Step-by-step explanation:
f(x) is the same as...y = 4x + 6....and then try to make x the subject of formula
y + 6 = 4x
x = (y + 6)/4....then when writing f^-1(x)...replace y with x
f^-1(x) = ( x + 6 )/4
Answer:
4x-3y-51=0
Step-by-step explanation:
y-
=m(x-
)
y-(-9) = 
(x-6)
3y+27=4x-24
4x-3y-51=0
Answer:
Step-by-step explanation:
we know that
The sides of a rhombus are all congruent and the diagonals are perpendicular bisectors of each other
so
Applying the Pythagorean Theorem
where
c is the length side of the rhombus
a and b are the semi-diagonals
we have
substitute the values
To find out the perimeter of the rhombus multiply the length side by 4
