2258 latex gloves
784 gloves remain
How many were used means we have to subtract
2258 - 784 = 1474
1474 gloves were used
Answer: (x+1)(3x+2) , i only got the answer for the first question, sorry!
Step-by-step explanation:
- factorise using AC method
AC= 3 x 2 = 6
find 2 numbers that add to give 5 and multiply to give 6 (3 and 2)
- put them as x in the equation to replace 5x
3x^2 + 2x + 3x + 2
- split the equation in half and expand each side
3x^2+2x | 3x+2
x(3x+2)+1(3x+2)
- put the numbers outside the brackets into a separate bracket
= (x+1)(3x+2)
Answer:
1.26
u(8) - u(2) = 0.74
Step-by-step explanation:
Given
u(x) = ∛x
where x is the number of pancakes consumed per week
and
u(x) is her utility (happiness)
If x = 8
u(8) = ∛8 = 2
Now, if x = 2
u(2) = ∛2 = 1.26
then
u(8) - u(2) = 2 - 1.26 = 0.74
