# Be to ? x 2 - 9x + = 6 -81/4 81/36 -9/2 81/4 X2-9x+ ___= 6

x2-9x+81/4=6

(This is because you need to do 2*x*a=-9x) Hence 2a=-9

So a=-9/2 hence a2= 81/4 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. 25
