expression 7(2j + 3 + 2j).
use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
Answers
Answer:
28j+21
Step-by-step explanation:
7(2j+3+2j)
Times everything in the ( ) by 7.
You should get (14j+21+14j)
Add 14j and 14j together.
And you get the answer.
7(2j+3+2j)
2j x 7 = 14j
3 x 7 = 21
2j x 7 = 14j
(14j + 21 + 14j)
14j + 14j = 28j
28j + 21 is the answer
Write an explicit formula for a , the nth term of the sequence 7, 14, 28, ...
Answers
Answer:
The sequence 7, 14, 28, ... is a geometric sequence with first term 7 and common ratio 2. The explicit formula for a geometric sequence is a_n = a_1 r^(n-1), where a_n is the nth term, a_1 is the first term, and r is the common ratio. In this case, a_n = 7 (2)^(n-1).
Here are the first few terms of the sequence:
n = 1: a_1 = 7
n = 2: a_2 = 14
n = 3: a_3 = 28
n = 4: a_4 = 56
n = 5: a_5 = 112
As you can see, the formula works for all values of n.

Greg made a small sign to advertise his school’s activity night. The sign was 15 1/2 inches wide and 11 inches long. Gloria made a longer banner to let students know about the activity night. Her poster was also 15 1/2 wide but it was 44 inches long. How many times larger is the area of Gloria’s banner than Greg’s sign?
Answers
Using the area of a rectangle, it is found that the area of Gloria’s banner is 4 times larger than the area of Greg's sign.
What is the area of a rectangle?The area of a rectangle of length l and width w is given by:
[tex]A = lw[/tex].
For Greg, the sign was 15 1/2 inches wide and 11 inches long, hence the area in square inches is given by:
[tex]A_{gr} = 11 \times 15.5 = 170.5[/tex]
For Gloria, the poster was 15.5 inches wide and 44 inches long, hence the area is of:
[tex]A_{gl} = 44 \times 15.5 = 682[/tex]
The ratio is given by:
[tex]r = \frac{A_{gl}}{A_{gr}} = \frac{682}{170.5} = 4[/tex]
The area of Gloria’s banner is 4 times larger than the area of Greg's sign.
