Answer:
c lololololo
Step-by-step explanation:
All you gotta do is subtract both of the numbers to get how much you need.
93 - 75 = 18
We can double check to see if it's right by using addition
18 + 75 = 93
Sonny needs to borrow 18$ to meet his required amount :D
One side of the rectangle is x=2, the other side is 2x-5
Add up all the four sides: (x+2) +(x+2)+(2x-5)+(2x-5)=54
6x-6=54
x=10
#3: suppose the first integer is x, then the second one is x+2
x(x+2)=255
x^2 +2x -255 =0
factor the quadratic equation: (x+17)(x-15)=0
x=-17, which is impossible, or x=15
so the two positive integers are 15 and 17
Answer:
The number of sides the polygon have 9
Step-by-step explanation:
Given in question as :
For The circle , the central angles measure be 40 °
Let the number of sides of polygon = n
Now . as we know
External angle = 
Or , 40° =
Or, = 40°
Or, = 40°
So, n = 
= 9
Hence The number of sides the polygon have 9 Answer
