Identify the value for the variable

-12, 4

Step-by-step explanation:

7^-9 x 7^-3 = 7^-12

When you multiply exponents with the same base, you add them.

11^-4/11^-8 = 11^4

When you subtract exponents with the same base, you subtract the exponent in the numerator by the exponent in the denominator.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
