Answer:
Step-by-step explanation:
We have the following quadratic equation
The factored expression will have the following form
Where b and c are two real numbers which when added together result in -1, and multiplying them results in -20
You can verify that the numbers that meet this condition are:
-5 and 4
Then the factors are:
Answer:
- 3rs
Step-by-step explanation:
6rs — 7bc (-) 9rs — 7bc = 6rs - 7bc - 9rs - 7bc
=6rs - 9rs - 7bc - 7bc (collecting the like terms)
= - 3rs
Answer:
station A
Step-by-step explanation:
Given data
We are told that she has $85 and she wants to fill only her tank
station A
charges $2.67 per gallon
12 gallons will cost
=12*2.67
=$32.04
station B
charges $2.60 per gallon
12 gallons will cost
=12*2.60
=$31.2
station C
charges $2.62 per gallon
12 gallons will cost
=12*2.62
=$31.44
The cheapest is station A
