The total power of the variables for the one term expression is 3 + 2 + 5 = 10. Hence, the degree is 10.
Possible values of x is -4 or -16

How to solve?</h3>
+ 20x +100 = 36
+ 20x + 100-36 = 0
+ 20x + 64 = 0
Using middle term split
In this method splitting of middle term in to two factors, In Quadratic Factorization using Splitting of Middle Term which is x term is the sum of two factors and product equal to last term.
+ 4x + 16x + 64 = 0
x(x+4) + 16(x+4) = 0
taking common (x+4)
(x+4)(x+16) = 0
Either
x+4 = 0
⇒ x = -4
or (x+16) = 0
⇒ x = -16
Thus possible values of x is -4 or -16

Answer:
AC = √105 ≈ 10 cm (nearest whole number)
Step-by-step explanation:
Use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse of a right triangle)
Give one of the legs = 4cm and the hypotenuse = 11 cm:
⇒ 4² + AC² = 11²
⇒ 16 + AC² = 121
⇒ AC² = 121 - 16
⇒ AC² = 105
⇒ AC = ±√105
As distance is positive, length of AC = √105 ≈ 10 cm (nearest whole number)
