What is the sign of the product (–7)(–2)(–5)(1)?

positive, because the products (–7)(–2) and (–5)(1) are negative, and the product of two negative numbers is positive
positive, because the products (–7)(–2) and (–5)(1) are positive, and the product of two positive numbers is positive
negative, because the product (–7)(–2) is positive, and the product (–5)(1) is negative and the product of a positive and a negative number is negative
negative, because the products (–7) (–2) and (–5) (1) are negative and the product of two negative numbers is negative

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
