Answer:   2x^{2} - 10x -28

Step-by-step explanation:

We know that f(x) = 2x +4     and g(x) = x -7    so to find f(g(x)) multiply them.

(2x + 4)(x-7)      Apply the distributive property twice

2x(x-7)

2x^2 - 14x  

4(x-7)  = 4x - 28  

2x^2 - 14x + 4x -28

2x^2 -10x - 28

Elan Coil [88]

Answer:

x=16

Step-by-step explanation:

the remaining angle for thw triangle is found by subtracting the already shown angles from 180 (the angle some of a triangle) which happens to be 96 to get 84 but now you need to subtract 84 from 180 to find the angle on the other side of line because lines have a total angle measurement of 180 but we already kbow what this get's us because it's 96 now we devide 96 by 6 to get 16 our answer.

(4x^5 + 3x^2 – x^4) +(6x^2 - 2x^5)
Monica [59]

Answer:

The simplified equation is as follows 2x^5 -x^4 + 9x^2

Step-by-step explanation:

Remove the parentheses around each equation and pair like exponents together

4x^5 - 2x^5 - x^4 + 3x^2 + 6x^2

Then combine the like terms

2x^5 - x^4 + 9x^2

It is in that order due to the proper form being to go from the highest to lowest exponents in an answer

Answer:

N$12 576. 11

Step-by-step explanation:

Loss%=10%

S.P= N$11 480.50

C.P =?

Loss%=100(C.P - S.P)/C.P

10=100(C.P-11 480.50)/C.P

10C.P=100C.P - 1 148 050

1 148 050=100C.P - 10C.P

1 148 050=90C.P

C.P=N$12 576.11
