Find the value of c that makes the expression a perfect square trinomial.<br><br> x2 + 4x + c
masha68 [24]

the value of c that makes the expression a perfect square binomial is c=4 .

<u>Step-by-step explanation:</u>

Here we have , an expression x2 + 4x + c or , x^2 + 4x + c . We need to find  the value of c that makes the expression a perfect square binomial. Let's find out:

We have ,  x^2 + 4x + c

⇒ x^2+4x+c

⇒ x^2+2(2)x+c

Now , we know that (a+b)^2=a^2+2(a)(b)+b^2

Comparing above equation  , to  x^2+2(2)x+c we get ;

⇒  x^2+2(2)x+c            { c=2^2  }

⇒  x^2+2(2)x+2^2

⇒  (x+2)^2

Therefore , the value of c that makes the expression a perfect square binomial is c=4 .

Why do we say that light travels in straight lines? Is it strictly accurate to say that a laser beam provides a per- fectly stra
Aliun [14]

Answer:

Step-by-step explanation:

Light is considered to be without mass, but it has energy. According to Einstein, energy can be

equivalently presented as mass. Mass is also affected by gravity, but near planets, this effect is

so small that it can be ignored and so we say that light travels in a straight line.

The above statement does not hold true when light passes near a star. A star possesses a very

high gravity field that bends light such that the change of direction is observed.

Explain how you can find the y-intercept of a linear equation and how that is different from finding the y-intercept of a geomet
Gnesinka [82]
The Y-Intercept of a line is the point where a line's graph intersects (crosses) the Y-axis. A y-intercept of 3 means that a line's graph intersects the Y-axis at the point (0,3). A y-intercept of -4 means that the graph of a line crosses the Y-axis at the point (0,-4).
