A because the alternate exterior angles equal each other
Answer:
(number - mean)/standard deviation.
Plug in the 78 for the number, the 84.5 for the mean, the 3.1 for the standard deviation.
Step-by-step explanation:
Yes it is because the negative is in parrenthases
Hello!
To find the perimeter of any rectangle, use the formula P = 2l + 2w.
In this formula, l is the length and w is the width. Given that the width is 2x + 9 and the length is x + 4, we can find the perimeter.
P = 2(x + 4) + 2(2x + 9)
P = 2x + 8 + 4x + 18
P = 6x + 26
Therefore, the perimeter of the rectangle is 6x + 26.
Answer:
2
Step-by-step explanation:
4 x 12 = 6 x 4 x n
Which gives
48 = 24n
48/ 24 = n
so n = 2
