First, we need to find the area of the rectangular playground.
To do this, we must multiply 40 by 10.
We get 400 meters².
Now divide 400 by 200 and you get 2.
That means 2 bags will be needed to cover the entire area of the playground.
To find the price, multiply 30 by 2.
The total cost for this project will be $60.
Hope this helped you out! :)
He used 16 oz of dark chocolate........he used 2/5 to make frosting....meaning he used 3/5 for the brownies.
2/5(16) = 32/5 = 6.4 oz for frosting
3/5(16) = 48/5 = 9.6 oz for the brownies
Therefore, he used (9.6 - 6.4) = 3.2 more oz in the brownies then in the frosting
The side is (2x+3)? then the area is:
(2x+3)(2x+3) = 4 x^2 + 12 x + 9 if x = 6 then
Area = 4(36)+12(6)+9
= 144 + 72 + 9
= 225, too big :(
Answer:
Step-by-step explanation:
The polynomial is simplified by combining like terms. Like terms are identified more easily if the variables in each term are written in the same order. We usually like to use alphabetical order. Two of the like terms have opposite coefficients, so they cancel. The result is ...
(3 1/2 -2 1/2)xy² +(-2 4/5 +2 4/5)x²y
= xy² . . . . simplified expression
__
For x = 1, y = -2, the value of the expression is ...
(1)(-2)² = 4
