perimeter = adding all of the numbers
Answer:
-5120
Step-by-step explanation:
a = 10
r = -2
Tenth term: 10(-2)⁹
= -5120
Answer:
Step-by-step explanation:
-x/4 <7
Multipy both sides by 4
4 (- x /4 ) < 7 . 4
Simplify
- x < 28
Multiply both sides by - 1 ( inverse the inequality)
( -x ) ( -1 ) > 28 ( -1 )
Simplify
x > - 28 Answer D
Answer
7. 30
8. 54
Step-by-step explanation:
For 7 do 2x+3x=90 because it is a right angle
then solve for x and get 15
to get the angle you are looking for multiply 2 by 15
and get the answer 30
For 8 to find the value of x you would need to...
add (4x+6) + (11x-6)= 180 because 180 is a straight angle.
Then simply solve for x and get 15x=180 which equals 12
The to get the angle you plug it in to (4x+6) and get the answer 54
