1) Which expression is equal to 10 x(13)
A. 10 + (1+3)
B. (10 x 1)+3
C. 10 + (1x3)
- D. (10 * 1)3

None of the expressions in the option is equal to 10 x(13).

Step-by-step explanation:

The answer can be verified by calculating the values of the expression in the question, those of each options, and then compare as follows:

Value of the expression = 10 x (13) = 10 x 13 = 130

Therefore, we have:

A. 10 + (1+3) = 10 + 4 = 14 130

B. (10 x 1)+3 = 10 + 3 = 13 130

C. 10 + (1x3) = 10 + 3 = 13 130

D. (10 * 1)3 = 10 * 3 = 30 130

Based on the calculations above, none of the expressions in the option is equal to 10 x(13).

the one that has a slope of 1/2 and is positive.
