Ican't quite remember how to approach this one, i have three others, but i think i could solve them if someone walked me through this one to jog my memory.

solve the quadratic equation by completing the square.

x^2-10x+12=0

first, choose the appropriate form and fill in the blanks with the correct numbers.
then, solve the equation.
(x+[])^2=[]
(x-[])^2=[]

if there is more than one solution, separate them with commas.

solution:

x = []

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
