Without multiplying, determine the sign of the product (−247,634)(183,758).

Negative

Step-by-step explanation:

It would be a negative number because a postive number multiplied by a negative number always equals a negative number

 The sign of the product is negative because a negative multiplied by a positive is a negative.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

thats not a system of equations, that is a solution
