Factor out the common term 2

2(x^2 - 4x - 12) = 0

Factor x^2 - 4x - 12

2(x - 6)(x + 2) = 0

Solve for x;

<u>x = 6, -2</u>

I believe your answer is B.37 because if u make the x a 5 like shown in the equation it now looks like h(5)=8(5)-3 so now you solve it and i got 37 i hope this helps you!<span />

Divide the following problem by hand (long division).
Genrish500 [490]

Answer:

Quotient = 122.88 and Remainder = 0

Step-by-step explanation:

Given:

Dividend = 3072

Divisor = 25

Please find the complete division in the attachment:

Step 1: when Dividend is 3072 and divisor is 25 we will first multiply divisor by 1 and subtract from first 2 digit of dividend which is 30 we get remainder as 5.

Step 2: Now bring another digit of dividend down so dividend will 57 and divisor is 25 so we will multiply divisor by 2 we get 50 we would subtract from 57 we get remainder as 7.

Step 3: Now bring another digit of divisor down so dividend 72 and divisor is 25 so we will multiply divisor by 2 we get 50 we would subtract from from 72 we get  remainder as 22.

Step 4: now dividend is 22 and divisor is 25 that means dividend is less than divisor so we will add decimal to quotient which adds 0 to dividend we get dividend as 220 and divisor is 25 now multiplying divisor by 8 we get 200 now subtracting it  with 220 we get remainder as 20.

Step 5: Now add 0 to dividend dividend will become 200 and divisor is 25 so we will multiply divisor by 8 we get answer as 200 now subtracting with dividend 200 we get remainder as 0.

Hence Quotient = 122.88 and Remainder = 0.
