Answer:
the answer is 3x2-10x+6=0
Answer:
B
Step-by-step explanation:
x²+2x=19 add 1 to both sides which gives you x²+2x+1=20
x²+2x+1 is the same as (x+1)²
Therefore (x+1)²=20
Answer:

Answer:
Step-by-step explanation:
In a parallelogram, the diagonals bisect each other.
4x - 5 = 3x
4x -3x = 5
x = 5
Answer:
a. The remaining length of the candle varies from <u>10 </u>inches to <u>5.5</u> inches
b. Remaining Length = 13 - b
Step-by-step explanation:
b.
The remaining (unburnt) length of the candle must be equal to the difference between total length of the candle and the burnt length of the candle. So, the expression for the remaining length can be written as:
Remaining Length = Total Length - Burnt Length
where,
Total length = 13 inch
Burnt Length = b
Therefore,
<u>Remaining Length = 13 - b</u>
<u></u>
b.
Now, we use the same expression for:
burned length = 3 inches
Therefore,
Remaining Length = 13 inches - 3 inches
Remaining Length = 10 inches
Now, for
burned length = 7.5 inches
Therefore,
Remaining Length = 13 inches - 7.5 inches
Remaining Length = 5.5 inches
Hence,
<u>The remaining length of the candle varies from 10 inches to 5.5 inches</u>
