Answer:
24x³-62x²+49x-12
Step-by-step explanation:
We can start by multiplying the first two brackets together first.
(3x-4)(2x-1)(4x-3) = (6x²-3x-8x+4)(4x-3)
Evaluate like terms.
(6x²-3x-8x+4)(4x-3) = (6x²-11x+4)(4x-3)
Multiply the two brackets together.
(6x²-11x+4)(4x-3) = 24x³-18x²-44x²+33x+16x-12
Simplify.
24x³-18x²-44x²+33x+16x-12 = 24x³-62x²+49x-12
Tell me if you need it in factorised form.
Answer:
2km/hr
Step-by-step explanation:
Given the following
Speed of boat in water = 5km/hr
Speed of boat against stream = 3km/hr
Since the speed of boat is going against that of the stream, hence, the speed of the stream will be the difference between the speed of boat and that when the boat is against the stream
Speed of stream = 5km/hr - 3km/hr
Speed of stream = 2km/hr
hence the required speed of stream is 2km/hr
Your answer is A if i did my calculations correct. go with A!
Answer:
21 kWh
Step-by-step explanation:
1. Subtract 25% from the original amount.
25% of 28 kWh is ...
0.25 × 28 kWh = 7.00 kWh
Subtracting this from 28 kWh, we find the usage after reduction to be ...
28 kWh - 7 kWh = 21 kWh
__
2. We know that if we reduce 100% of a quantity by 25%, then the resulting amount is (100 -25)% = 75% of the original. As a fraction, this is 75/100 = 3/4 of the original amount. Then the reduced usage is ...
(3/4) × (28 kWh) = 3·(7·4)/4 kWh = 3·7 kWh = 21 kWh
__
Mario must reduce his usage to 21 kWh or less.
