Find the sum of h^2+ 4h - 4 and 5h^2– 8h+2

  6h^2 -4h -2

Step-by-step explanation:

(h^2 +4h -4) +(5h^2 -8h +2)

= h^2(1 +5) +h(4 -8) +(-4 +2) . . . . group like terms

= 6h^2 -4h -2

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

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
