Answer:
see explanation
Step-by-step explanation:
The area (A) of the square = s² ( s is the measure of the side )
Here s = x + 2 and A = 7 , thus
(x + 2)² = 7 ← expand left side using FOIL
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
It has to be either A or B
The answer is 225
15•15=225
The mean is 14
add all the numbers up and divide the sum by 6 because that’s how many numbers you’re adding together.
12+10+14+18+14+16
= 84
84/6 = 14
