Answer:
(x + 4)^2 + 3 = 0
Step-by-step explanation:
When you multiply out (a + b)^2, you get a^2 + 2ab + b^2. We already know the a^2 term, which is x^2. We can deduct the first term of the square is x because x * x is x^2, and x would correspond with a. Next, we can connect the 2ab term with 8x, as it includes the variable x.
2ab = 8x
We have established a = x, so:
2xb = 8x
b = 4
We can put this together to get the square:
(x^2 + 8x + 16) + 3 = 0
(the three is added to get a last term of 19 in the given equation)
When we factor the square, it turns out as:
(x + 4)^2 + 3 = 0
Note: Sorry if the answer was a bit confusing, this is kinda hard to explain.
Because no perfect squares are factors of 37, the most simplified that the square root of 37 can get is
√37, or approximately 6.08
The correct answer is 16 not 14 not or 12
Answer:
Step-by-step explanation:
Let x be the number of cola bottles.
Henry picks 3 times as many smarties as cola bottles, then he picks 3x smarties.
He also picks twice as many marshmallows as smarties. Then he picks
marshmallows.
In total, there are
sweets in the bag.
Marshmallows are
of all sweets in the bag.
