Answer:
x = - 2, x = 7
Step-by-step explanation:
Given
f(x) = 4x² - 20x - 56
To find the zeros let f(x) = 0, that is
4x² - 20x - 56 = 0 ( divide through by 4 )
x² - 5x - 14 = 0 ← in standard form
(x - 7)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 7 = 0 ⇒ x = 7
If your friend now has 18 that means you had 48, as mentioned above, you had given half of your tokens, half of 48 is 24. =24
Answer:
5, 10, 15
Step-by-step explanation:
the increase in the sequence is 5 so since it starts from 0 which you can find out because 25 is the 5th sequence and that means that +2*5 =25 . x=0
0+ 5 = sequence 1
0+ 5+5 = seq 2
0+5+5+5= seq 3
