Given the polynomial 21x 4 + 3y - 6x 2 + 34 what polynomial must be subtracted from it to obtain 29x 2 - 7 ? what polynomial must be added to it to obtain a first degree polynomial?

Well you know 29x2-7=now add

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
