Answer:

see below

Step-by-step explanation:

19. (4x + 8x² - 8) + (x² + 7 - 4x)

= 4x + 8x² - 8 + x² + 7 - 4x

= 8x² + x² + 4x - 4x -8 + 7

20. (7x² - 11 + 16x) + (5x - 3x² - 7)

= 7x² - 11 + 16x + 5x - 3x² - 7

22. (4x² - 12x - 10) - (2x² + x - 3)

= 4x² - 12x - 10 - 2x² - x + 3

23. (7x³ - 9x² - 14x) - (4x³ - 4 - x)

= 7x³ - 9x² - 14x - 4x³ + 4 + x

= 7x³ - 4x³ - 9x² - 14x + x + 4

25. (9x² + 24x - 8) - (5x² + 3x + 10)

= 9x² + 24x - 8 - 5x² - 3x - 10

26. (5x - 12x² + 9x³) - (5x³ + 6x - 3)

= 5x - 12x² + 9x³ - 5x³ - 6x + 3

28. (2x² - 1 + 3x³) + (5 - 13x - 11x²)

= 2x² - 1 + 3x³ + 5 - 13x - 11x²

30. (10x - x² + 8) + (5x² + 1 - 22x)

= 10x - x² + 8 + 5x² + 1 - 22x

What is the value of g(2)?

n200080 [17]

Answer:

g(2)=1

Step-by-step explanation:

We need to use the second definition of the function since x=2

g(2) = 2^3 -9(2)^2 +27(2) -25

= 8-9(4) +54 -25

= 8-36+54-25

= 1

Answer:

x = 17

Step-by-step explanation:

Since the triangles are congruent, the angles are equal

I≅ P

3x+4 = 72-x

Add x to each side

3x+4+x = 72-x+x

4x+4 = 72

Subtract 4 from each side

4x+4-4 = 72-4

4x= 68

Divide by 4

4x/4 = 68/4

x = 17

What is the value of s in the equation

galben [10]

The answer is B. 16 because you multiply 4 with 2s and -1 so the new equation will be 8s-4=7s+12 and you have to subtract the variable 7s to 8s the equation will be 1s-4=12 and add 4 to 12 and it gives you 16 and just divide 16 and one and you answer should be 16. :)
