Use the distributive property to write an expression that is equivalent to each given expression. 1. -3(2x-4) 2. 0.1(-90+50a) 3. -7(+50a) 4. 4/5(10y+-x+-15)

We need to apply distributive property on each of the given expressions to write their equivalent expressions.

(1)  

Upon using distributive property, we get:

(2)

Upon using distributive property, we get:

(3)

This part is incomplete.

(4)

Upon using distributive property, we get:

all it means is function 3

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.
