The formula for finding the area of a square is:
The formula for finding the area of a triangle is:
So for the square the area would be:
The area for the triangle would be:
Ok, so the bigger box has sides that are multiples of 4.5 inches:
18in * 9in * 4.5in.
in terms of the cubes that go inside them, the bigger box is:
4 box * 2 box * 1 box, so you know that 8 boxes fit inside.
Answer:
hey plss stop this is not for funny games this is only for questions in schol and answer
Step-by-step explanation:
but congrats you found a dream dreram well
Answer:
see below
Step-by-step explanation:
1.the equations have different slopes? They will intersect at one point so one solution
2.the equations have the same slope and different y-intercepts. They are parallel lines with a different y intercept so they will never intersect - no solutions
3.the equations have the same slope and same y-intercepts. they are the same line so they have infinite solutions
Answer:
4x - 36 feet
Step-by-step explanation:
The area A of a square whose sides are s units is given as
A = s * s
Given that the area A = x^2-18x+81, factorizing
A = x^2-9x-9x+81
A= x(x-9)-9(x-9)
A = (x-9)(x-9)
A = (x-9)^2
This means that the size of each side of the square courtyard is x-9 feet long
Recall that the perimeter P of a square whose side is s long is given as
P = 4s hence since the side of the courtyard is x - 9 feet, the perimeter of the courtyard
P = 4(x-9)
= 4x - 36 feet
