Answer:
She didn't put the sign's in the proper place, it should be ( x + 3 ) ( x - 7 )
Step-by-step explanation:
( x - 3 ) ( x + 7 ) = x² + 7x - 3x - 21 = x² + 4x - 21
( x + 3 ) ( x - 7 ) = x² - 7x + 3x - 21 = x² - 4x - 21
Answer:
LeBron trimmed for 1 hour and mowed for 2 hours
Step-by-step explanation:
Let t represent the number hours LeBron trimmed. Let m represent the number of hours LeBron mowed. The problem statement tells us two relationships:
m = 2t . . . . . LeBron spent twice as many hours mowing as trimming
(5.50 +5.00m) + (3.50 +6.50t) = 25.50
Substituting for m and collecting terms, we have
9.00 + 16.50t = 25.50
16.50t = 16.50
t = 1
m = 2·1 = 2
LeBron spent 1 hour trimming and 2 hours mowing.
