Which polynomial lists the powers in descending order?
ооо
o a. х + 4х + 2x4 - 4х5 - 10
в. -10 + 4х3 – 4х +24+7
с. 4х2 – 4х + 2 x x - 10
o d. х - 4х + 2 + 4х – 10

The construction of copying qpr is started below. the next step is to set the width of the compass to the length of ab. how does this step ensure that a new angle will be congruent to the original angle? by using compass take the measures of angle and draw the same arc according to it.
