9 seconds
F(t)=0
0= -16t^2+144t
Than solve for “t”
t=0 or t=9
And 0 seconds doesn’t make sense so it is 9 seconds
Answer is 4 i know this answer because we do that as practice in high school
The answer to this equation is 25a - 40b - 10
Steps:
−17b +a + −23b + 24a + −10
Combine like terms. In this case, the like terms would be ( -17b + -23b) and (<em>a</em> + 24a)
−17b + a + −23b + 24a + −10
Eliminate the addition symbols as it's not necessary anymore.
25a + - 40b + - 10
= 25a - 40b - 10
It is the letter G because when you add 12, 34 27 ,36,42 ,15 28,32 47,30 you get 330 which then you divide by the number of numbers which is 11 - 330 divided by 11 equals 30
