Answer:
D. 49
Step-by-step explanation:
When completing the square, you take the value after x^2 which is 14 and divide it by 2 which equals 7 for which you then square that number which 7 times 7 = 49
The price of of the hotdog to the price of popcorn is in the ratio 5:4
25:20 is 5:4
Neither are correct.
Navene has broken the problem up and simply added numbers together to get "4577"
Annabelle is also wrong because whereas she multiplied, she also broke up the numbers in the equation to get "46710"
The answer should be 18,690,300
Without any more information we can't find the actual numerical representation of the length and width but we can give an expression that will allow us to find them...
We let the width equal x, so the length is 3x. That would be the dimensions...
length = 3x
width = x
So to find perimeter the expression would be
2(3x) + 2(x) =
6x + 2x =
8x
For the area it would be
a= length × width
a = 3x × x
a = 3x^2
