Answer:
We have a1 = 27 and r = 3 (because 27:9 = 3; 9:3 = 3; 3:3 = 1);
Then s = 27 / (1 - 3) ;
Finally, s = - 27 / 2;
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
substitute the values that are given into the expression.
c + a = x
12 + 3 = x
15 = x
Let x be the age of ishaan so the age of ben will be 12+x. the equation will become x=x+12
Going 3 years back, the age of ishaan was x-3 so that of ben would be x+12-3 before 3 years. at that time the age of ben was 4 times the age of ishaan. it means x+12-3(the age of ben)=4(x-3(the age of ishaan))
solving this equation, we get the answer x=7. this is the age of ishaan in the present.
Answer: undefined in both cases.Explanation:1) Expression to evaluate:

2) You are asked to evaluate that expression for two different cases,
x = 0 and x = 3.3) First case:
x = 0The expression cannot be evaluated at x = 0, because the
denominators (both denominators)
equal 0, and the division by 0 is not defined.
So, the answer is
undefined.
4) Second case,
x = 3When you replace x = 3 you get:

Again, this result in a
division by 0, so you conclude that it is
undefined too.
