15n-18. This is 3(5n-6) because 3 times 5n is 15n and 3 times 6 is 18.
Answer:
55
Step-by-step explanation:
Number of Jone's goats = 550
Let Number of King's goat = x
Jone's goat is 10% more than King's ;
Thus, number King's goat would be ;
x = 550 - (10% of 550)
x = 550 - 55
x = 495
x = Mr. King's goat
Hence, Jones goat is :
550 - 495 = 55 more than Mr King's goat.
Area covered by the forest in the beginning = 1500km²
Decrease in area each year = 5.8% = 5.8/100 × 1500 = 87km²
Decrease in the area of the forest in <em>t</em> years = 87t
Area of forest now = y
y = 1500 - 87t
Multiply the factors together. You should get the original expression.
For example, if we are to factor
2x^2 + 4x
we would factor as
2x(x + 2).
Check this by multiplying back in
2x*x + 2x*2 = 2x^2 + 4x
which is what we started with, so we know we are correct.
