Question

(6-p)²+9(p-5). p=0,4​

Answer 1

Ответ:

(6-p) ²+9(p-5) при p=-0,4

(6-(-0,4))²+9(-0,4-5)=  (6,4)²+9*(-5,4)=40,96-48,6= -7,64    

Answer 2

упростим выражение. раскроем скобки по формуле квадрата разности. приведем подобные.

...=36-12р+р²+9р-45=р²-3р-9.

подставим при р=0,4.

0,4²-3*0,4-9=0,16-1,2-9= –10,04

Answer 3

To evaluate the expression (6-p)² + 9(p-5) when p = 0 and p = 4, we substitute the values of p into the expression and simplify it.

Let's start by evaluating the expression when p = 0:

(6 - 0)² + 9(0 - 5) = 6² + 9(-5) = 36 + (-45) = -9

Now, let's evaluate the expression when p = 4:

(6 - 4)² + 9(4 - 5) = 2² + 9(-1) = 4 + (-9) = -5

Therefore, when p = 0, the expression evaluates to -9, and when p = 4, the expression evaluates to -5.
