4a + 3 - 9 = -7 + 2 + a
4a - 6 = -5 + a
4a - a = -5 + 6
3a = 1 / : 3
a = 1/3

Answer: -√46 is between -7 and -6</h3>
==========================================================
Explanation:
List out the perfect squares
- 1^2 = 1
- 2^2 = 4
- 3^3 = 9
- 4^2 = 16
- 5^2 = 25
- 6^2 = 36
- 7^2 = 49
- 8^2 = 64
and so on. We can see that 46 is between 6^2 = 36 and 7^2 = 49.
We can say 6^2 < 46 < 7^2
Applying the square root to all three sides leads us to 6 < sqrt(46) < 7
Now multiply all three sides by -1. This will flip the inequality signs
We go from
6 < sqrt(46) < 7
to
-6 > -sqrt(46) > -7
It might help to order things from smallest to largest to get this
-7 < -sqrt(46) < -6
This means -sqrt(46) is between -7 and -6 on the number line

Step-by-step explanation:
Answer: (A) 2(x + 4)
Step-by-step explanation: We know that the measure of one side of the square is (x + 4). But, we first will need to find the total area and perimeter of the square in order to find the difference between them.
The area is length x width, so multiply 2(x + 4) Since all the sides are the same.
2(x + 4) = 2x + 8. The area is 2x + 8.
To find the perimeter simply add x + 4, four times. 4(x + 4).
4(x + 4) = 4x + 16 as the total perimeter of the square.
Now subtract the area from the perimeter.
4x + 16 - (2x + 8) --Distribute negative sign.
4x + 16 - 2x - 8 --Combine like terms
4x - 2x + 16 - 8
2x + 8.
2(x + 4) is equivalent to 2x + 8 and is therefore the answer.
