True: adding two polynomials will always result in another polynomial
Answer:
468 square feet.
Explanation:
The lateral surface of the foam pit can be calculated as:
Lateral Surface = Perimeter Base x Height
So, the perimeter of the base can be calculated as:
Perimeter = 12 ft + 24 ft + 12 ft + 24 ft
Perimeter = 72 ft
Therefore, the lateral surface is equal to:
Lateral surface = 72 ft x 6.5 ft
Lateral surface = 468 ft²
Then, 468 square feet will be painted red.
There are 21 red pens. For every 3 red pens, there is 1 blue pen.
Let's make these into a fraction equation.
21/p=3/1
p is the number of blue pens we have yet to find.
First, cross multiply.
21x1=21
px3=3p
Now, we have an equation of
21÷3p
We set it equal to 1, and we solve it.
21÷3p = 1
(21÷3p)×3p=1×3p
21=3p
21÷3=(3p)÷3
7=p
So, if there are 21 red pens, there are 7 blue pens.
We add these together to find the total number of pens the teacher has.
21+7=28
The teacher has 28 pens total.
6.438 is the final answer
My guess would be...
