C never, there are always different methods to solve a problem but don't forget that the equation always stays the same!
Hello :D
$40.00 x 3 = $120.00
$20.00 x 2 = $40.00
$120.00 + $40.00 = $160.00
$400.00 - $160.00 = $240.00
There is $240.00 left in the account.
X² + 4x + 4 = 25
(x+2)² = 25
x + 2 = <span>±5
x + 2 = -5 or x + 2 = 5
x = -5 -2 x = 5 - 2
x = -7 x = 3
</span><span>The solutions are x=-7 and x=3</span>
Answer:
1740 miles
Step-by-step explanation:
They drive the way twice; once they go there and then they go home. Therefore, 870 times 2 equals 1740.
(-3, 1.5)....simply add the x coordinates together, divide them by two, and then do the same for the y coordinates.
