25 = -16t^2 + 50t + 4
16t^2 - 50t + 21 = 0
16t^2 - 8t - 42t + 21 = 0
8t(2t - 1) - 21(2t - 1) = 0
(8t - 21)(2t - 1) = 0
8t - 21 = 0 or 2t - 1 = 0
t = 21/8 or t = 1/2
t = 2.625 or t = 0.5
Answer:
-5, 4.1, 4.7, 16 squared
Step-by-step explanation:
negative numbers are always the least, then 4.1 is less than 47/10 which is 4.7 and 16 squared which is 256, then we have 4.7 because that is less than 256 which is the greatest number.

b 612 like only football.
<span>Determine the x- and y-intercepts of each line x+3y=24
+ x=0, so y= 24:3=8 and we have </span><span>y-intercepts is 8
</span>+ y=0, so we have x=24, x<span>-intercepts is 24
