Hello!
When multiply binomials together, we should use the FOIL method.
The FOIL method is an acronym for First, Outer, Inner, and Last.
First, let's set up the expression.
(7x - 1)(3x - 2)
Now, we can multiply in accordance with the FOIL method.
First: 7x · 3x = 21x²
Outer: 7x · -2 = -14x
Inner: -1 · 3x = -3x
Last: -1 · -2 = 2
Now, we simplify the inner terms.
21x² - 14x - 3x + 2
21x² - 17x + 2
Therefore, the area of the rectangle is 21x² - 17x + 2.
109.93 lbs
since the quantities vary directly, then
w(moon) = kw(earth ) ← ( k is the constant of variation )
to find k use the given condition
k = w( moon ) / w( earth ) = 
given w(earth) = 218.24
w(moon) = 
= 109.93
The answer is 248 cups in 15.5.
Hope this helps,
