When you think of domain, you always think x-values. so the domain values for this graph is (-∞,∞).

This is a graph of sine. Domain is equal the set of all real numbers:

$D=\mathbb{R}=(-\infty,\ \infty)$

The domain is x-y, for which there is a graph.

Square of a binomial x^2+2x+1

garik1379 [7]

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.

Answer both question for 20 points and brainliest

Answer:

1 - c

2 - A

Step-by-step explanation:

Hey There!

So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume

Remember to find the volume we use the equation

V = length x width x height

so we just plug in the values

v = 2.6 x 2.1 x 3.9 = 21.294

the closest is 20 so C is your answer

For the second one we are given a triangular prism

and they want us to find the volume

$V=\frac{1}{2} bhl$

b = base (10.3)

l = length (4)

h = height (7)

7x4=28

28x10.3=288.4

then we divide by 2

288.4/2=144.2

so your selected answer is correct
