I don't know what your asking
Answer:
Step-by-step explanation:
5r + 2b = 14 (5 lbs of oranges and 2 lbs of bananas = $14)
3r + 6b = 18 (3 lbs of oranges and 6 lbs of bananas = $18)
Let's use the elimination method. Multiply the first equation by -3:
-15r - 6b = -42
3r + 6b = 18
-----------------
12r = 24
Divide by 12:
r = 2
42/12 = 3.5, 63/18 = 3.5, therefore we will be multiplying the last time by 3.5. 40x3.5= 140, and therefore, the number of pencils produced in 40 seconds is 140

Answer:
-6xy
Step-by-step explanation:
(2x-y)x(x-2y)-(x+2y)X(2x-y)
remove the parentheses
2x^2-4xy+xy-2y^2-(2x^2-xy+4xy-2y^2)
collect terms
2x^2-4xy+xy-2y^2-(2x^2+3xy-2y^2)
remove the parentheses
2x^2-4xy+xy-2y^2-2x^2-3xy+2y^2
remove the opposites, collect the terms to get -6xy
