A. and x = 9
To solve the equation, you would need to isolate the variable, so the first step would be to add six to each side.
2x = 18
Then, divided each side by 2 to get the value of x.
x = 9
Answer:
yes alby is correct
Step-by-step explanation:
Answer:
=-1+\sqrt{15}i,\:x=-1-\sqrt{15}i
Step-by-step explanation:
<span>The area of a blade with rectangular shape = 1/2 * b * h where b is the base and h, the height.
Here b = 7 and height = 4
So the area of the blade = 1/2 * 7 * 4 = 14ft^2
If the are four blades the total area is the summation of individual blade.
So area = 14 + 14 + 14 + 14 = 56ft^2. Hence none of the option satisfies the answer.</span>
