The correct answer would be A.36.
Hope this helps;)
27.) Because the area is 60, we know that the two side lengths, x and x + 4 will multiply to equal that.
In other words,
x(x+4) = 60
Distribute the x
x^2 + 4x = 60
Complete the square:
1.) Take the middle term, 4, divide it by 2, then square it. You get 4 again.
2.) Add 4 on both sides of the equation:
x^2 + 4x + 4 = 64
3.) Factor the left side, you'll find that it is a perfect trinomial.
(x + 2)(x + 2)= 64
4.) Simplify (x + 2)^2 = 64
5.) Square root both sides:
(x + 2) = +/- 8
Because side lengths cannot be negative, it must be positive 8.
6.) x + 2 = 8
7.) Subtract 2 on both sides, you'll see that x = 6 :)
Answer:
I may be wrong but 8 cups of chocolate
Step-by-step explanation:
First I looked over what I needed to do, 1 cup of cream and 2 cups of chocolate.
The next thing I did was attempt to solve it in 2 different ways, the first one being adding 1 cup of cream and 2 cups of chocolate every time, but that didn't work. The second attempt I just kept 1 cup of cream and added 6 cups of chocolate.
I added 6 because there are already 2 cups of chocolate, so that would add up to 8 cups. We didn't add any cups of cream so its still one. 8+1 is obviously 9.
Sorry if I am wrong
