What value for c will make the expression a perfect square trinomial x2-7x+c

The value of c is 12.25

Step-by-step explanation:

we know that

A perfect square trinomial is of the form

In this problem we have

so

equate the equations

we have

the following equations

-----> equation A

and

-----> equation B

Solve the equation A

Solve the equation B

therefore

The value of c is 12.25

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
