Given:
u varies directly with the square of p and inversely with d.
To find:
The equation for the given situation.
Solution:
If y is directly proportional to x, then
If y is inversely proportional to x, then
It is given that u varies directly with the square of p and inversely with d. So,
It can be written as:
Where, k is the constant of proportionality.
Therefore, the required equation is 
.
Answer:
yes
Step-by-step explanation:
half of x which is 4 = y which is 2
you keep doing that with the rest of the xs and ys
Answer:
(x+2) (x+2)
Step-by-step explanation:
X^2+4x+4
X^2+2x+2x+4
x(x+2) +2(x+2)
(x+2) (x+2)
Answer:
25
Step-by-step explanation:
Simplify 84/100 to get to 21/(?). To get to 21 you'd divide 84 by 4 so you'd have to do the same thing to the denominator. 100 divided by 4 is 25, therefore there were 25 questions.
