Answer:

20, 60, 15

Step-by-step explanation:

Let the third number be n, then

The first number is n + 5 and the second number is 4n

Sum the 3 numbers and equate to 95, that is

n + 5 + 4n + n = 95 ← collect like terms on left side

6n + 5 = 95 ( subtract 5 from both sides )

6n = 90 ( divide both sides by 6 )

n = 15

Thus

The first number is 15 + 5 = 20

The second number is 4 × 15 = 60

The third number is 15

Which represents x2 – 12x + 36 in factored form?
alexandr402 [8]

Answer:

(x - 6)(x - 6)

Step-by-step explanation:

The given quadratic equation is $ x^2 - 12x + 36 = 0 $.

A quadratic equation can be factored in the form $ (x - a)(x - b) $ where $ -a $ and $ -b $ will form the roots of the equation.

Here the roots are: $ +6 , +6 $.

The factored form would simply be:  $ (x - 6) (x - 6) $.
