kelli and her faimly went to the beach for a vacation. they drove 293 miles 7 hours to get theredid they drive each hour
Inessa [10]
Ok so, Since Kelli and her family drove a total of 293 miles in 7 hours, then your equation should be \frac{293miles}{7hrs} 
Now, since you have your ratio you divide 293 by 7 in order to get how many miles were driven in one hour
\frac{293}{7} = 41.85714286 miles/hr

Show that one zero of 8x230x27 is the square of the other.
murzikaleks [220]

Answer:

8x2-30x+27 has one root (9/4) the square of the other (3/2)

Step-by-step explanation:

8x2+30x+27 = (2*x+3)*(4*x+9)  => solution = {-3/2, -4/9}

One is not the square of the other because squares are positive.

8x2-30x+27 = (2*x-3)*(4*x-9)  =>

solution = {3/2, 4/9}   since (4/9 = (3/2)^2, therefore the preceding question is correct.
