Answer:
p = (105-2l)/13
Step-by-step explanation:
4l + 26p = 210
Isolate 26p by subtracting 4l from both sides
26p = 210-4l now divide by 26
p = (210-4l)/26 you can simply
p = (105-2l)/13
(g-f)(x) is x² - 3x - 6
<u>Step-by-step explanation:</u>
Step 1:
Given g(x) = x² - 1 - 2x, f(x) = x + 5. Find (g-f)(x)
(g-f)(x) = x² - 2x - 1 - (x + 5) = x² - 2x - 1 - x - 5 = x² - 3x - 6
