Answer:
x=4
Step-by-step explanation:
(2x+3)^2=121
2x+3=square root of 121
2x+3=11
2x=11-3
2x=8
x=4
(in a square all sides are equal therefore area =length ×width where length and width=2x+3)
Answer:
2/3x-6
Step-by-step explanation:
Using the Fundamental Counting Theorem, the number of possible telephone numbers is given by:
a) 900,000.
b) 78,125.
c) 10,000.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

For item a, a multiple of 100 means that the last two digits are 00, hence the parameters are:

Hence the number is:
N = 9 x 10^5 = 900,000.
For item b, odd digits are 1, 3, 5, 7 and 9, hence the parameters are:

Hence the number is:
N = 5^7 = 78,125.
For item c, if the first 3 digits are 277, the parameters are:

Hence the number is:
N = 10^4 = 10,000.

Hi!
I can help you with joy!
- Remember, the Distributive Property states that

- Now, let's use this property to solve our problem:
- 3(x+6)
- According to the property, we have to distribute 3 and multiply it by everything inside the parentheses:
- 3*x + 3*6
- 3x+18 (Answer<em>)</em>
Hope it helps.
