Ageneric x*x grid has c blocks moved to create a(x-c) by a(x+c) grid. which of the following equation represents the difference of squares for this situation

X^2 - (X-c) (X+c) = c^2

Step-by-step explanation: If the original square is x by x, then it is X^2. We remove one row from a side, and add it to another row, leaving c^2 as the remainder.

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
