Step-by-step explanation:
By substituting x = 0.4 in equation 7 + (-3x^2)
= 7 - 3 (0.4)^2
First solving o.4^2 as per the rule of BODMAS
= 7- 3 (0.16)
Now multiplying -3 with 0.16
= 7 - 0.48
= 6.52 THIS IS THE ANSWER
Answer:
the awnser would be a(g(x)=3x2
27). 8a+7
28). 10k-1
29). 2n-48
30). x+16
31). 14b+3c-3
32) -2y=10
