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:
y=(x+7)2(2x+1)(x−4)
y=2x4+21x3−4x2−399x−196
Step-by-step explanation:
The answer would be 98
7+7=14
14•7=98
