You need to add the problem you need help with....
Differentiate it
get f ' (x)=3x^2-4
put 3x^2-4=0
x=2/√3,-2/√3
so interval
x∈(-2/√3,2/√3)
Answer:
I think it is either 85 or 51 because the question was not specific
Step-by-step explanation:
I am not entirely sure if you mean Jose changed jobs or added a new job on top but i will do both.
34/2=17
17+34=51
OR
51+34=85
180cm. The square is 6 x 6 = 36 and the triangles = 12 x 6 = 72 and then divide it by 2 = 36 multiply that by 5 and you get 180cm
