Answer:
2x + 6
Step-by-step explanation:
The area of a square is the square of the side length:
A = s²
We know that the area of the square is 4x² + 24x + 36.
4 is 2², and 36 is 6². 24 is double 2 times 6.
Therefore, this is a perfect square trinomial:
A = 4x² + 24x + 36
A = (2x + 6)²
Therefore:
s = 2x + 6
14 + (-8) / 2 x -3
Follow order of operations: divide and multiply from left to right:
-8/2 = -4 x -3 = 12
Now you have 14 + 12
The answer is 26
The answer is six because you have to subtract the upper and lower quartile which are 18 and 16 in this case
Answer:
x = -42 is your answer
Step-by-step explanation:
x/6 = -7
Isolate the x. Note the equal sign, what you do to one side, you do to the other.
Multiply 6 to both sides
(x/6)(6) = (-7)(6)
x = (-7)(6)
Simplify. Multiply 6 with -7
x = (-7)(6)
x = -42
