If u answer, can u tell me how u did it. thx.

whenever you get charged for a phone service, you'd notice it usually says "so many hrs for so much money", but in short is just the quotient of each  unit, namelhy either hr/$ or $/hr.

the first company charges $10/3.5hr, so the rate is their quotient,  approximately $2.86/hr, namely $2.86 per hour.

the second company charges $1.25/(1/2)hr, so their quotient is $2.5/hr, namely $2.5 per hour.

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
