anzhelika [568]

Answer:

Step-by-step explanation:

your basically multiplying everything in the first parenthesis by everything in the second parenthesis

(x + 4y + z)(x - 7y) =

x(x - 7y) + 4y(x - 7y) + z(x - 7y) =....keep in mind, 4yx is the same as 4xy

x^2 - 7xy + 4xy - 28y^2 + zx - 7zy....combine like terms

x^2 - 3xy - 28y^2 + zx - 7zy <---- your answer

this is the distributive property

2 doctors is what % of 25 doctors

Elanso [62]

For this case we propose a rule of three:

25 ------------> 100%

2 --------------> x

Where the variable "x" represents the percentage equivalent to 2 doctors.

$x = \frac {2 * 100} {25}\\x = 8$

Thus, 2 doctors represent 8% of 25

Answer:

2 doctors represent 8% of 25
