Answer:
C. 2x + 12
Step-by-step explanation:
2(10) + 2(x-4)
= 20 + 2x - 8
= 2x + 20 - 8
= 2x + 12
5mm
using the formula of volume of cone i.e. 1/3 ×πr²h
1/3 × πr²h = 314
or, r²= (314×3)/ (π×h)
or, r² = 25
r= 5 mm
A complex fraction is. Fraction at a whole number
B
logₓ 7 = 3
x³ = 7
Take cube root both sides
5²+10²=25+100=125
13²=169
so 5²+10²≠13²
so it is not a right angled triangle.
