Decide if the expressions below are equal or not equal. Then choose the correct answer below that has the correct supporting reason. 3m + 4(m + 12) and 7m + 12

a. Yes, both expressions simplify to be 7m + 12
b. Yes, both expressions can be factored
Selected:c. No, the expressions cannot be simplifiedThis answer is incorrect.
d. No, the expression on the left can be simplified to 7m + 48

(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
