Since one hour = 45 years, one minute should be 1/60th of 45 years because 60 minutes = an hour.
45/60 = 3/4
So one minute would be 3/4 of an hour, or 45 minutes.
Hope this helps!
(k - 1)(k - 4)
Use FOIL to solve this.
First
k * k
Outer
k * -4
Inner
-1 * k
Last
-1 * -4
k^2 - 4k - 1k + 4
k^2 - 5k + 4 is the trinomial.
B=48/7 you simplify 7/b(b) to 7b/6
Then multiply both sides by 6 so 8 x 6 =7b then simplify 8 x 6 =48
And divide both sides by 7 48\7 then switch sides b=48/7
