Answer:
Sammy is 8 years old
Step-by-step explanation:
3s + 4 = 28 is the equation you need to use you have to get s on its own to find Sammy's age
3s + 4 = 28 subtract 4 from both sides
3s = 24 divide both sides by 3
s = 8 Sammy is 8 years old
So if it is 3x^2+4x=2 then
set one side to zero
subtract 2 from both sides
3x^2+4x-2=0
this is not factorable by normal means so use quadratic formula which is if you have the equation in ax^2+bx+c=0 form you can solve for x if you put it into this equation quadratic formula

so if you were to input it into this equation you would get
a=3
b=4
c=-2
the solution is

the answer is C

u switched parentheses
Cut five inches to creat the least amount of unused cardboard.
f(x) = 5x − 1 and g(x) = 2x^2 + 1
(f × g)(x) = (5x − 1)(2x^2 + 1)
(f × g)(x) = 10x^3 - 2x^2 + 5x - 1
Substitute x = - 3
(f × g)(-3) = 10(-3)^3 - 2(-3)^2 + 5(-3) - 1
(f × g)(-3) = 10(-27) - 2(9) -15 - 1
(f × g)(-3) =-270 - 18 - 16
(f × g)(-3) = -236
Answer
- 236
