If alonzo is x then the equation is

x + (x +3) + 2(x + 3) = 57

Which equals

x + x + 3 + 2x + 6 = 57
4x + 9 = 57
4x = 48
x = 12

This means alonzo is 12 years old and alexis is 3 years older so alexis is 15 years old

Answer = 15 years old

Which of the following is the correct factorization of the polynomial below?<br> x3 + 14x2 + 49x
Naddika [18.5K]

For this case we must factor the following polynomial:

x ^ 3 + 14x ^ 2 + 49x\\

We can take common factor x:

x(x ^ 2+ 14x + 49)

To factor the expression within the parenthesis, we must find two numbers that when multiplied give 49 and when added together, 14 are obtained. These are: 7 and 7.

7*7=49,7+7=14

Thus, the expression is factored as:

x(x + 7)(x +7)

Answer:

x (x + 7) ^ 2
