(4x + 2)(4x - 2) = 16x^2 - 8x + 8x - 4
Combine like terms 16x^2 - 4
Explanation
Just multiply the each term in the first parentheses by the other terms in the second parentheses.
Answer:
14 units. as it tells you.
The answer is
LA to Page: 611 mi
Page to Denver: 406 mi
Total distance from LA to Denver is T.
The distance LA to Page is x
The distance Page to Denver is y.
T = x + y
T = 1017
______
x + y = 1017
<span>The distance from L.A. to Page (x) is 205 miles greater than the distance from Page to Denver (y):
x = y + 205
The system of two equations:
</span>x + y = 1017
x = y + 205
Substitute x from the second equation into the first one:
y + 205 + y = 1017
2y + 205 = 1017
2y = 1017 - 205
2y = 812
y = 812 / 2
y = 406 mi (Page to Denver)
x = y + 205 = 406 + 205 = 611 mi (LA to Page)
The probability of those sequence of events is 2/21
