Answer:
The answer is B
Step-by-step explanation:
only 20 chars.....
It can have a parameter of 60 if it is 3in wide and 27 in long.
We find this by looking at the factors of 81.
3 and 27 are factors and if using the formula given we see that length = 30-3 = 27.
Using these factors of 81, the parameter would be 27 + 27 + 3 + 3 which results in 60.
Answer:
(a) x = -0.418 , -3.581
(B) c = 6.855, -1.855
Step-by-step explanation:
(A) We have given equation
On comparing with standard quadratic equation
a = 2, b = 8 and c = 3
So roots of the equation will be
(b)
a = 1, b = -5 and c= -14
So
2) the answer is b. 56
3) the answer is c. 48 - not sure
4) the answer is d. 8
5) the answer is 3/2
6) the answer is a. 1
