Answer:
(15+(3-6))x4
Step-by-step explanation:
1. 3-6 = -3
2. 15+-3 = 12
3. 12x4 = 48
Assuming that the equations are (x+7) and (3x-8) because the first equation does not have a sign these are the steps. When you multiply you will get 3x^2+21x-8x-56. After this you will simplify and you will get your final answer which is 3x^2+13x-56. Also if I used the wrong equations please let me know and I can help you with the correct ones.
Answer:
C) -8cos 3xsin x
Step-by-step explanation:
To express -4(sin4x - sin2x) as a product, we use the formula sinA - sinB = 2cos[(A + B)/2]sin[(A - B)/2.
Comparing sin4x - sin2x with sinA - sinB, A = 4x and B = 2x.
Substituting these into the equation, we have
sin4x - sin2x = 2cos[(4x + 2x)/2]sin[(4x - 2x)/2
sin4x - sin2 x = 2cos[6x/2]sin[2x/2]
sin4x - sin2x = 2cos3xsinx
So, -4(sin4x - sin2x) = -4(2cos3xsinx) = -8cos3xsinx
So, -4(sin4x - sin2x) = -8cos3xsinx
Thus, the answer is C
Answer:
y = -4x - 22
Step-by-step explanation:
m = -4
using (-6,2)
Slope-intercept: y = mx + b
2 = -4(-6) + b
2 = 24 + b
b = -22
y = -4x - 22
