Answer:
i think its 5, use the magic numbers of pythagoras theorem to help u it might not be correct, use at ur own risk
Answer:
SA = 16x^2 +30x+6
Step-by-step explanation:
The surface area is given by
SA = 2 (lw + lh + wh)
The length is 2x, the width is (x+3) and the height is (2x+1)
SA = 2 ((2x)*(x+3) + (2x)*(2x+1) + (x+3) (2x+1))
We need to distribute
SA = 2 ((2x^2+6x) + (4x^2+2x) + (2x^2 +6x+x+3))
Combine like terms
SA = 2 (2x^2+ 4x^2+2x^2+6x+2x +6x+x+3)
SA = 2 (8x^2+15x+3)
Multiply by 2
SA = 16x^2 +30x+6

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.
They form a proportion when both of the ratios are equivalent.
An example: 3/15 and 1/5 is a proportion because the are equivalent.
The reason why they are equivalent is because if you cross multiply meaning doing 3*5 which equals 15 and 15*1 which equals 15 so basically you multiply the numerator by the other fractions denominator and do the same for the other side and see if the numbers are the same if they are not the same they are not a proportion if they are the same they are a proportion.
Hope this helps!
