To put an equation into (x+c)^2, we need to see if the trinomial is a perfect square.
General form of a trinomial: ax^2+bx+c
If c is a perfect square, for example (1)^2=1, 2^2=4, that's a good indicator that it's a perfect square trinomial.
Here, it is, because 1 is a perfect square.
To ensure that it's a perfect square trinomial, let's look at b, which in this case is 2.
It has to be double what c is.
2 is the double of 1, therefore this is a perfect square trinomial.
Knowing this, we can easily put it into the form (x+c)^2.
And the answer is: (x+1)^2.
To do it the long way:
x^2+2x+1
Find 2 numbers that add to 2 and multiply to 1.
They are both 1.
x^2+x+x+1
x(x+1)+1(x+1)
Gather like terms
(x+1)(x+1)
or (x+1)^2.
Well the ratio would be 8:24, or in reduced form, 1:3. you would solve it by taking sale of strawberry yogurt for the first half of the ratio, and then adding up all of the values to get the total.
I think it’s B but don’t at me
Answer:
3.26 hours
Step-by-step explanation:
speed = distance / time
595 = 1940 / t
t = 1940 / 595 = 3.26 hours
or
Well, as you can see the answer and problem are switched so u do this
24=2k
÷2 ÷2
----------------------
12=k. check:
12×2 is 24☆
happy to help.
