Answer:
hello : x = 2
Step-by-step explanation:
note : a^3 = b^3 : a=b
x^3-8=0
x^3=8
x^3= 2^3
so : x=2
Answer:
C 10 columns and 12 rows
Step-by-step explanation:
c = columns
r = rows

The answer is C
If you are trying to say what is square root of 100 then it is 10. Like 10^2 equals 100.
Answer:
90
Step-by-step explanation:
Let x be Dany's score in geography. His score in chemistry is double his score in geography and it is equal to
2 x
The average of all four scores is 79. Hence
(93 + 88 + x + 2 x) / 4 = 79
Multiply both sides of the equation by 4
4×(93 + 88 + x + 2 x) / 4 = 4×79
Simplify
93 + 88 + x + 2 x = 316
Group like terms
3 x + 181 = 316
Solve for x
3 x = 135
3 x / 3 = 135 / 3
x = 45
score in geography = x = 45
score in chemistry = 2 x = 2 × 45 = 90
