For question 1 of my polynomials homework, do i have to divide the fractions? the expression is "8/2 + 3/4x^2 - 2/5x." for the answers we have to do a, b, and c. a is the expressions in standard form, b is the degree, and c is the leading coefficient. i know how to do all of these, but i'm not sure whether or not i have to divide the fractions.

Do 8/2 and multiply by 2/5 then take that awnser divide it by 7 and multiply it by 3/4

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
