8 x² + 64 x = 0
x · ( 8 x + 64 ) = 0
x = 0,  or:  8 x + 64 = 0
                 8 x = - 64
                 x = - 64 : 8
                 x = - 8
Answer :  x = 0, or x = -8

Morgarella [4.7K]

Answer:

19,500 - (1,000 x 12) = X

Brianna earns $ 7,500 more than Lisa per year.

Step-by-step explanation:

Given that Brianna earns $ 19,500 per year and Lisa earns $ 1,000 per month, to write a numerical expression that represents how much more Brianna earns per year than Lisa the following calculations and equations must be performed:

19,500 - (1,000 x 12) = X

19,500 - 12,000 = X

7,500 = X

Thus, Brianna earns $ 7,500 more than Lisa throughout the year.

What value of x satisfies this equation (5x + 20) = 2
FrozenT [24]

Answer:

x equals -3.6

Step-by-step explanation:

5 something +20 is supposed to be 2, so you take the two off of the 20 and get 18, then divide the 18 by 5 and you'll get 3,6 and logically since it needs to be negative you need the minus before it.
