Answer:

The value of the expression for x=2 is 2.

Step-by-step explanation:

Consider the provided expression.

$4(x - 3) + 5x - x^2$

We need to find the value of expression for x=2.

Substitute the value of x=2 in provided expression and simplify as shown.

$4(2 - 3) + 5(2) - 2^2$

$4(-1) + 10 - 4$

$-4 + 6$

$2$

Hence, the value of the expression for x=2 is 2.

Artyom0805 [142]

Step-by-step explanation:

1) x/20 = -9

By cross multiplication,

x = -180

2) -168 = -14k

k = -168/-14

k = 12

3) -5m = -50

m = 10

4) -320 = -20n

n = 16

5) -4 = x - 5

x = 1

6) -6(-8 + n) = -54

42 - 6n = -54

-6n = -54 -52

6n = 106

n = 17.6

7) 3(x - 9) = -3

3x - 27 = -3

3x = 24

x = 8

8) 9k + 3 = -78

9k = -81

k = -9

9)4 + (n/4) = 8

By taking LCM,

16 + n/4 = 8

16 + n = 32

n = 16

10) -5r + 7 = -73

-5r = -80

r = 16

Hope it helps.
