Answer:
x = 37
Step-by-step explanation:
i just check it with a protractor, if 37 is the answer then that means " (4x - 20) degrees" is 143.
143 + 37 = 180
i think the answer is probably x = 37
If 6cm=12ft, then if you reduce that you get 1cm=2ft so multiply each measurement by 2 getting 9cm=18ft, 7cm=14ft, 10cm=20ft, 8cm=16ft
Answer:
29. (5,0) and (-7/2,0)
30. (-1,0) and (5/7,0)
Step-by-step explanation:
29. y=2x² - 3x - 35
y = (x-5)(2x+7)
y is 0 at x = 5 and -(7/2)
31: y=-7x² - 2x + 5
y = -(x+1)(7x-5)
y is 0 at -1 and 5/7
See the attached graph.
Answer: 5x-13-(4x+2x)
