Answer:
p=7
Step-by-step explanation:
pqrs equal to tuv perimeters =60
triangle=20×3
60
Trapezium=(p+8)+12+12+3p
60=4p+32
4p=28
p=7
This solution might become quite complex.
Please try to keep up with me, and I'll go slowly:
You said (x + k) = (x + k - 1) (x + k)
Divide each side by (x+k): 1 = (x + k - 1)
Add 1 to each side: 2 = (x + k )
Subtract 'k' from each side: 2 - k = x
Answer:
Step-by-step explanation:
The surface area of this cylinder consist of two circles and a 3D outer edge with respect to the circumference. The area of a circle is given as 
. Using 
as requested in the problem, the area of both these circles is:
.
The 3D outer edge is then 
.
The area of this 3D outer edge is represented by 
. Therefore, we set up the following equation:
.
It's C. because 3n -8 is the minus 8 that Liza has so it = 13
