Answer:
2x^2-6x-4
Step-by-step explanation:
(7x2 + 4x - 9)
-(5x2 + 10x - 5)
=
7x^2-5x^2=2x^2
4x-10x=-6x
-9-(-5)=-4
thus, your answer is 2x^2-6x-4
Answer:
5100 cm of wax will make 17 candles
Step-by-step explanation:
Each candle is 5 cm long, 4 cm wide, and 15 cm tall
to know the space they cover, we divide it with their volume and since they are in rectangular prism
Volume is length x width x height
5 x 4 x 15 = 20 x 15 = 300cm
1 candle = 300cm
what number of candle is represented as x
1 candle comprises of 300cm wax
x = 5100
300x = 5100 x 1 =5100
300x= 5100
x= 5100/300 = 17
5100 cm of wax will make 17 candles
5 dollars per hour
because 15 divided by 3 is 5.
The correct answer is ∠Y = 75°
because
45°∠A ∼ ∠X
∠B ∼ ∠Y = 75°
60°∠C ∼ ∠Z
45 + 60 = 105
180 -105 = 75
Answer:

Step-by-step explanation:
can be solved by just multiplying the numerators together and the denominators together
2 * 3 = 6 and 5 * 4 = 20 so the answer would be 
This simplifies to
