WILL GIVE BRAINLIEST!! Which polynomial does this sum of tiles represent?
+
A. x^2 + 2x+7
B. x ^2+ 3x + 3
C. 4x^2 + 3
D. 2x^2 + 4x + 7

+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

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
