Answer:
6
Step-by-step explanation:
3x+11 = 29
3x = 29 - 11 = 18
x = 18/3 = 6
Answer: A) 150
You put all the numbers in numerical order, than you get the middle number of both halves which will be 300 and 450, so you find the difference of that which is 150
Simplifying the given expression, it is found that Curtis is correct.
<h3>How to simplify the expression?</h3>
The expression to be simplified is given by:
[4(10) - 3²] + 6(4)
The non-related operations can be solved first, hence:
[4(10) - 3²] + 6(4) = [40 - 9] + 24
For the square, we have to consider that:
- For -x², the negative is not part of the square, hence the result is negative, as - x*x = -x².
- For (-x)², the negative is part of the square, hence the result is positive, as (-x)*(-x) = x².
The first bullet point is the reason that -3² = 9. Then, the simplified expression is completed as follows:
[40 - 9] + 24 = 31 + 24 = 55.
Which means that Curtis is correct.

#SPJ1
Step-by-step explanation:
Geometric mean is the square root of the product.
√(9 × 11) = √99 ≈ 9.950
A. Isn't the answer because 9 can't go into 60
B. This is your answer 45 inches
C. and D. can't be the answer because 15 can't go into 50 or 36
15 * 3 = 45
9 * 5 = 45
I hope this helps you out, I had taken me a while to figure out what it was asking. ^-^
