Answer:
Step-by-step explanation:
First: multiply both sides by 4. 4 times c is 4c and the other sides cancels out as you are doing the inverse operation of division
Then, you have 
Subtract both sides by a squared
DO NOT TAKE THE SQUARE ROOT! This is because it is a squared plus 3b so you have to do the inverse of addition
From that you get 
Finally, divide both sides by 3.
You get
Answer:
sorry i couldnt help
Step-by-step explanation:
:(
The minimum number of rolls that can be bought is 4.
The first step is to determine the perimeter of the ceiling and the length of its hypotenuse.
Perimeter of the ceiling = perimeter of a square = 4 x length = 4 x 16 = 64 ft
The hypotenuse is the distance from one corner of the ceiling to the other corner of the ceiling. The hypotenuse would be determined using the Pythagoras theorem.
The Pythagoras theorem: a² + b² = c²
where a = length
b = base
c = hypotenuse
16² + 16²
= 256 + 256
= 512 feet
c = √512 = 22.6 feet
Total length = 22.6 feet + 64 feet = 86.63 feet
Minimum number of rolls = 86.63 / 25 = 3.46 = 4

Answer:
Perhaps, she is interested in finding the area enclosed by this triangular park.
Step-by-step explanation:
The area of the triangle enclosed by the three points
A(1,1), B(1,4) and C(-3,4) in this question will be given by
|Ax ( By − Cy)+ Bx(Cy−Ay)+ Cx(Ay− By) |/2
=|1(4-4)+1(4-1)+-3(1-4)|/2=10/5= 5 sq. units.
