Let A={x|x<-3} and B={x|x<=0} is A a subset of B?

According to given case ;

Set A contains elements smaller than -3, and Set B has elements smaller than or equal to 0, therefore Set B includes the numbers smaller than -3 as well.

so, we can conclude that Set A is a Subset of Set B

The statement in the given question is correct ~

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
