Answer:
Step-by-step explanation:
<u>Perimeter of garden A is
</u>
- P = 2(w + l) = 2( 2x - 3 + 5(2x - 3)) = 24x - 36
<u>Perimeter of garden B is
</u>
-
5x + 5 + 4x + 2 + 8x - 8 = 17x - 1
<u>Sum of perimeters:</u>
- 24x - 36 + 17x - 1 = 41x - 37
The statement 2 is FALSE as number we got is different from the one in the statement
Answer:
Step-by-step explanation:
s^2 represents the area of a square whose side length is s.
(8x)^2 represents the area of a square whose side length is 8x.
Answer:
45 degrees
Step-by-step explanation:
Since all three angles would equal 180 degrees you would do 72 + 63 = 135. Then 180 - 135 = 45

Negative 4 is less than x because x is one and negative 4 is less than 1
Answers:
The second term is 2
The fifth term is 23
The ninth term is 51
-----------------------------------------------------------
Explanation:
To find the second term, replace every n with 2 and use PEMDAS to simplify
a(n) = -5+(n-1)(7)
a(2) = -5+(2-1)(7)
a(2) = -5+(1)(7)
a(2) = -5+7
a(2) = 2
The second term is 2
Similarly, plug in n = 5 to get the fifth term
a(n) = -5+(n-1)(7)
a(5) = -5+(5-1)(7)
a(5) = -5+(4)(7)
a(5) = -5+28
a(5) = 23
The fifth term is 23
Finally, replace every n with 9 to find the ninth term
a(n) = -5+(n-1)(7)
a(9) = -5+(9-1)(7)
a(9) = -5+(8)(7)
a(9) = -5+56
a(9) = 51
The ninth term is 51
