In your question that ask to calculate the area of one of the tiles if a semicircular archway in the front of the garden is using 8 congruent granite tiles and the area of one of the tiles is 2.9ft ^2. I hope you are satisfied with my answer and feel free to ask for more.
Answer:
A) 2b+24x
Step-by-step explanation:
7b+3x-5b+21x
7b-5b+3x+21x
2b+3x+21x
2b+24x
b=5, commutative property
c=3, associative property
Points on BC:
(-5, 5) and (0,1)
Slope = (5-1)/(-5-0)
Slope = -4/5
y = mx + c
y = -4/5x + c
at point (0,1)
1 = -4/5(0) + c
c = 1
y = -4/5x + 1
5y = -4x + 5
4x + 5y = 5 (Answer D)
