<span>f(x)=4x²-15x-25
</span><span>f(x)=(4x + 5)(x - 5)
</span><span>zero-product property
let </span>f(x)=(4x + 5)(x - 5) = 0
so
(4x + 5)(x - 5) = 0
4x +5 = 0
4x = -5
x = -5/4
x = -1.25
x - 5 =0
x = 5
answer
factor: (4x + 5)(x - 5)
x = 5 and x = -1.25
8, 14, 12, 17, 4, 6, 2
Mean = average = (8+ 14 + 12 + 17 + 4 + 6 + 2) / 63 = 63/7 = 9
Answer
Mean = 9
Answer:
158 & 318
Step-by-step explanation:
8+10=18
18+20=38
38+40=78
78+80=158
5x2=10
10x2=20
20x2=40
40x2=80
C=2πr
Divide by 2r
c/2r=pi
So pi equals c over quantity 2 times r
A+s=294
s=2a
Use substitution
a+2a=294
3a=294
a=98
Final answer: 98 adult tickets
