Hey there!

x^2 + 4x = 12

SUBTRACT 12 to BOTH SIDES

x^2 + 4x - 12 = 12 - 12

SIMPLIFY IT

x^2 + 4x - 12 = 0

FACTOR the LEFT SIDE of your EQUATION

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

• EQUATION #1: x - 2 = 0

OR

• EQUATION #2: x + 6 = 0

SIMPLIFY IT

• EQUATION #1 answer: x = 2

OR

• EQUATION #2 answer: x = -6

OVERALL ANSWER: x = 2 or x = -6

YOUR ANSWER: x = 2 (Option A.)

Good luck on your assignment and enjoy your day!

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.

Evaluate 3(2e+8) = 34
strojnjashka [21]

Answer:

e = 5/3

Step-by-step explanation:

3(2e+8) = 34

Distribute

6e +24 = 34

Subtract 24 from each side

6e +24-24 = 34-24

6e = 10

Divide each side by 6

6e/6 = 10/6

e = 10/6

Divide the top and bottom by 2

e = 5/3
