What is the value of
4x the power of 2 + 5x when x=1?

the answer is 21

Step-by-step explanation:

4x to the power of 2 + 5x

so: 4*1 the power of 2 +5*1

4to power of 2 +5

and 4 to the power of 2 equals 16 (because 4*4=16) and +5

so 16+5=21

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
