Answer:
164 inches
Step-by-step explanation:
Let the length of the new born be = x
Let the length of the adult be = y
y= 9x + 2
When x = 18,
y = 9 (18) + 2
= 162 + 2
= 164 inches
I would help but I learned this in 5th grade sorry but hope you find a answer!
Step-by-step explanation:
if you draw an imaginary perpendicular line across the figure from the vertex which joins the line of 2 cm with the line that is making an angle of X then you can see that this figure is made up of two figures that is a triangle and a rectangle.
now from the angle given i.e X.
perpendicular= 5 cm
base = 14 -2= 12 cm
hypotenuse= ?
we know that,
h² = p²+b²
= 5²+12²=169
h= √169
h= 13
again,
cos X = b/h
= 12/13
Answer:
answer would be B. I'm pretty sure!
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
Subtract 6 from both sides so the equation becomes 1/9x=2. Multiply by the reciprocal on both sides (9)1/9x=2(9).
This cancels out to x=18
