Answer:
x^2 +3x -504
Step-by-step explanation:
Sort of do what you'd do to solve but in reverse. You need 21 for a zero, so the binomial factor would be (x-21) since if you set that = to zero you'd get 21. Same for -24. The binomial factor would be (x+24) since that would give you -24. Now that you have the two binomials, you can just multiply them and get the quadratic. :)
Answer:
Step-by-step explanation:
tanx=27/38
take the inverse...
tan^-1(27/38)
≈35.4 degrees
12x + 20 = 4(3x + 5)
gcf = 4
Hi there!
Since the end time is 10:30 and the activity was started 3/4 an hour earlier, we need to subtract 3/4 an hour from 10:30 to get the starting time.
3/4 hour = 45 min
10:30 - 45 min = 9:45
So, the starting time is 9:45.
Hope this helps!
Perimeter:
add all sides
(1/2)+(1/2)+(1/2)+(1/2)+1+1 = 1+1+1+1 =4cm
