(trying to isolate/get x by itself in the equation)
5(x + 6) = 50 Distributive property [distribute 5 into (x + 6)]
5x + 30 = 50 Subtraction [subtract 30 on both sides of the equation]
5x = 20 Division [divide 5 on both sides]
x = 4
Subtraction then division, the 2nd option
Answer:
12x-3y
Step-by-step explanation:
10x3 + x + X
Group like terms
10x + x +X-3
Add similar elements: 10x + x + x = 12x
= 12x - 3y
Answer:
The first three nonzero terms in the Maclaurin series is

Step-by-step explanation:
GIven that:

The Maclaurin series of cos x can be expressed as :


From equation(1), substituting x with (4x), Then:

The first three terms of cos (4x) is:



Multiplying equation (2) with (3); we have :




Finally , multiplying 5 with
; we have:
The first three nonzero terms in the Maclaurin series is
