Question

21b-6b найди значение если b=13заранее спасибо!

Answer 1

21b - 6b, при b = 13;
15b;
Если b = 13, то 15 * 13 = 195.

Answer 2

To find the value of the expression 21b-6b when b=13, we simply substitute 13 for b in the expression and simplify:

21b - 6b (when b=13) = 21(13) - 6(13) (substitute 13 for b) = 273 - 78 (simplify by multiplying) = 195

Therefore, when b=13, the value of the expression 21b-6b is 195.
