Find the value of this expression if x = -2.
x^2 – 8/x + 6​

-1

Step-by-step explanation:

x^2 – 8

x + 6​

Let x = -2

(-2)^2 – 8

-2 + 6​

Exponents first

4 – 8

-2 + 6​

Then complete the numerator and denominator

-4

4

Then divide

-1

-1

Step-by-step explanation:

((-2)^2 - 8)/ -2+6

=>(4-8)/4

=>-4/4

=>-1

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

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
