Answer:
60inches
Step-by-step explanation:
3 times 4 equals 12. 12 times 5 equals 60. so the volume should be 60 inches.
Answer:
Step-by-step explanation:
Key to this method is remembering that
So, if you divide the coefficient of x by 2 and square it, that will complete the square. With that in mind, things are easy.
6/2 = 3, so add 
So, c=9
Similarly, for the other two,
You don't really have to worry about the sign, since squaring will always make it positive
Substitute 4 for y. Then -3x^2 + 16 = 52.
Solve for x. Subtract 16 from both sides, obtaining -3x^2 = 36.
Divide both sides by -3, obtaining x^2 = -12. This last result makes no sense, as no square of a real number could be negative. Probably this is where you're ":getting a negative answer."
If imaginary answers were allowed, then x = i*√12 = i*2√3 or x = -i*2√3.
x =
Answer:
36 cm^2
Step-by-step explanation:
S.A. = 2 (lw + wh + lh)
S.A. = 2 ((4)(2) + (2)(2) + (4)(2))
S.A. = 2 (8 + 4 + 6)
S.A. = 2 (18)
S.A. = 36
Answer:
No, every relation is not a function.
Step-by-step explanation:
Every function is a relation because there are two points (x,y) somehow related to each other.
But every relation is not a function
The given ordered pairs are the function
Since, we are getting different value of y for ecah x.
The condition for function is we should get different value of y for each x.
