Answer:
x= √10 and x= -√10
Step-by-step explanation:
first look to isolate the term with the variable on one side
-5 +5 -2x² = -5 -15; subtract 5 from both sides(inverse of addition)
-2x² = -20; divide both sides by -2 (inverse of multiplication)
x² = 10; square root both sides (the inverse of raising to power of 2)
√x² =√10
x =±√10

Answer:
0.249%
Step-by-step explanation:
Difference: 2010 - 2005 = 5
Increase = Difference / Starting point = 5 ÷ 2005 = 0.00249 or 0.249%
There would be $13410 because 4500 x 0.22 x 9 = 8910
4500 + 8910 = 13410
Answer/Step-by-step explanation:
43 = (4 * 101) + (3 * 100)
43 = (4 * 10) + (3 * 1)
43 = 40 + 3
