Answer:
x ≈ 14.5
Step-by-step explanation:
A = x²√(25+10√5)/4
A = 1.72a²
x² = A/1.72
= 363.27/1.72
≈ 211
x = √211
≈ 14.5
Answer:
672
Step-by-step explanation:
12 * 12 = 144
144* 14 = 2016
2016 / 3 = 672.
C=pi(radius)^2
c=pi(5)^2
c=pi(25)
c=78.5398163397...
c is about 78.5
Answer:
1,875 cm³
Step-by-step explanation:
first find the volume of the large rectangular prism, which is 2,000 cm³
Then find the volume of the small rectangle, which is 125 cm³
now subtract 125 from 2,000
which equals = 1,875
6a + 5 + x + 7x - 2a
Combine like terms.
4a + 5 + 6x
