Please give more clear explanation for this question so I can help you.
A = 5 + B
A + 5 = 2B
Let's get one of the variables on one side.
A = 5 + B
A = 2B - 5
By the transitive property
5 + B = 2B - 5
Solve for B.
5 = B - 5
10 = B
Use 10 = B in an earlier equation to find A.
A = 5 + B
A = 5 + 10
A = 15
Abe has 15$ and Ben has 10$.
Answer:
41x² - 27x + 27
Step-by-step explanation:
Perimeter of Rectangle:
= 2(20x²-12x+4) + 2(5x²-5x+15)
= 40x²-24x+8 + 10x²-10x+30
= 50x²-34x+38
Perimeter of Triangle:
= 6x²+6x+3x+3+3x²-2x+8
= 9x²+7x+11
Difference:
(50x²-9x²)+(-34x+7x)+(38-11)
= 41x² - 27x + 27

Answer:
SA = 108π cm²
Step-by-step explanation:
The surface area (SA) of a sphere is calculated as
SA = 4πr² ( r is the radius )
Thus the SA of a hemisphere is
SA = 
× 4πr² = 2πr²
The area of the circular base = πr²
Then total SA is
SA = 2πr² + πr² = 3πr² = 3π × 6² = 3π × 36 = 108π cm²
