Answer:
186
Step-by-step explanation:
The area is given by ...
(f • g)(3) = f(3) • g(3) = (3+3) • (12•3 -5) = (6)(31)
(f • g)(3) = 186
Answer:
x^3-10x^2+x+120
Step-by-step explanation:
Assuming you mean roots -3, 5, 8
These happen when we have (x+3)(x-5)(x-8)=0
Expand this
(x^2-2x-15)(x-8)=0
=x^3-2x^2-15x-8x^2+16x+120
=x^3-10x^2+x+120
Answer: 1 teashirt=7 L
1 hat= 3L
Step-by-step explanation:
2 T shirts= 31 - 17
2 T shirts= 14
1 T shirt=14/2
1 T = 7 L
14L+ 1H=17 L
one hat = 17 - 14=3 L
The three numbers have to multiply to 48 in a ratio of 3:2:1
which would be 6:4:2
so 6 inches
First term is -7, so a_1 = -7
To get the next term, we add on 4. We can see this if we subtract like so
d = (2nd term) - (1st term) = (-3) - (-7) = -3+7 = 4
So d = 4 is the common difference.
Apply a_1 = -7 and d = 4 to get...
a_n = a_1 + d*(n-1)
a_n = -7 + 4*(n-1)
a_n = -7 + (n-1)*4
