(3x+2) (x-7)
FOIL
first 3x*x = 3x^2
outer 3x*-7 = -21x
inner = 2*x = 2x
last 2*-7 = -14
add them together = 3x^2 -21x+2x -14
combine like terms 3x^2 -19x -14
Answer:
23 and 131
Step-by-step explanation:
For the first one. Since a whole entire angle thingie is 360, subtract 243 and 94 from 360. Answer is 23 :)
For the second one. This is a supplementary angle. 180- 49 is 131. Your done!
Answer: 8 feet
Step-by-step explanation:
Draw a right triangle and label the sides using the given information. (Drawing below) Use pythagorean theorem to find the missing length:
a^2 + b^2 = c^2
(building)^2 + (missing piece)^2 = (ladder)^2
6^2 + x^2 = 10^2
36 + x^2 = 100. subtract 36
x^2 = 64. square root of both sides
x = 8
1 UK fl oz = 28,413 ml
2 UK fl oz = 56,826 ml
If 5ml contains 160mg
56,826fl oz contains X mg
________________________
56,826 X 160 = 9,092,160
9,092,160 / 5 = 1818,432mg acetaminophen needed
