Which is the correct algebraic expression after combining like terms? 6+8x-7-x A.) 7x-1
B.) 7x+13
C.) 9x-1
D.) 9x+13

A.) 7x-1

Step-by-step explanation:

It would be this because 8x-x = 7x and 6-7 = -1, so if you combined them you should get 7x - 1

6 +8x -7 -x

8x -x = 7x

6-7 = -1

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
