7. 3c+3=84
3c=81
c=27
So either 81/3 but if simplified its 27/1
8. The correct answer would be 55=31+t
100 and -100 are the two solutions for the square root of 10,000
Answer: D, an equilateral triangle has three congruent sides.
I am only guessing that you mean:
(n-2)/-3<7 if so, multiply both sides by -3 (and reverse the direction of the inequality sign because of negative mulitplication!)
n-2>-21 add 2 to both sides
n>-19
Answer:
2010
Step-by-step explanation:
volume of a cube= hxlxw
5x5x5=125
V=πr2h
π10^2x6=1884.9=1885
1885+125=2010
