If A = 3x + 5x - 6 and B = -2x² – 6x + 7, then = A-B equals

1 -5x? - 11x + 13

2 5x + 11x – 13

3 -5x? – x + 1

4 5x? – x +1

Distribution Method

(- xª +2r³ + 3x²) - (2r4 + 5x³ + x²)

a. she will receive a refund of $278.

step-by-step explanation:

probability for j is 1/4

while

a is 1/6

(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
