Answer:
(X+6)x(X-3)
Step-by-step explanation:
X^2+6X-3X-18
Xx(X+6)-3(X+6)
(X+6)x(X-3)
big X is the variable
small x is multiplication sign
If we let p and t be the masses of the paper and textbook, respectively, the equations that would best represent the given in this item are:
(1) 20p + 9t = 44.4
(2) (20 + 5)p + (9 + 1)t = 51
The values of p and t from the equation are 0.6 and 3.6, respectively. Thus, each paperback weighs 0.6 pounds and each textbook weighs 3.6 pounds.
