Answer:

Therefore the two negative integers are - 22, - 14.

Step-by-step explanation:

Given that, two negative number are are 8 units apart.

Let x be a negative integer one of them.

Then the another integer be (x+8)

Given that the product of them is 308.

According to the problem,

x(x+8)=308

\Rightarrow x^2+8x=308

\Rightarrow x^2+22x-14x-308=0

\Rightarrow x(x+22)-14(x+22)=0

\Rightarrow (x+22)(x-14)=0

\Rightarrow x=-22,14

Since x is a negative integer.

∴x = - 22.

Then another integer is =( - 22+8) = -14

Therefore the two negative integers are - 22, - 14.

Four times the amount of money in my bank account plus $200 is still two
ioda

Answer:

$700

Step-by-step explanation:

So, I like to extract the information we know and form it into an equation.

So we know that after multiplying what you have in the bank by 4, then add 200 dollars you get two thousand dollars less than a fourth of what's in your dad's bank account.

Your dad has $20,000 in the bank.

Before we write the equation let's find what two thousand less than a fourth of 20,000 is.

20,000/4 = 5,000

Now, 5,000 - 2,000 = 3,000

Ok let's say x is how much money you have

So:

4x + 200 = 3,000

we can isolate the variable by subtracting 200 from both sides

4x = 2,800

then we can divide by 4 on each side

x = 700

so you have $700 in the bank
