You know that 12x=60, and that x=5. Which property of equality would you use to conclude that 12•5=60?
alexandr402 [8]

ANSWER

The substitution property of equality.

EXPLANATION

We know that:

12x = 60

and that

x = 5

Since x=5 or 5=x , we can substitute x for 5 wherever we see x in the given equation.

When we do that, we obtain;

12 \bullet \: 5 = 60

This is what we refer to as the substitution property of equality.

Factor completely x2 + 20x − 36.
vodomira [7]

Answer:

Prime

Step-by-step explanation:

x² + 20x − 36

You must find a pair of numbers that multiply to give -36 and add to give +20.

The likely candidates are 2 and 18, and they must have opposite signs to give a negative product.

+2 × (-18) = -36; +2 + (-18) =   -16

-2 ×   18  = -36;  -2 +     8   = +16

Neither combination gives +20 as the sum.

The expression can't be factored with rational numbers.

The expression is prime.
