Which statements are true? select each correct answer. 15m3−6m=3m(5m2−6m) 32m4+12m3=4m3(8m+3) 6m2+18m=6m2(1+3m) 40m6−4=4(10m6−1)

Option (b) and (d) are correct.

b)

d)

Step-by-step explanation:

Given: Some statement

We have to check which statements are true.

We will check all one by one.

Consider

a)

Consider the Left hand side of the given statement,

Taking 3m common from each term, we have,

Thus, LHS ≠ RHS

Thus, the statement is false.

b)

Consider the Left hand side of the given statement,

Taking common from each term, we have,

Thus, LHS = RHS

Thus, the statement is True.

c)

Consider the Left hand side of the given statement,

Taking 6m common from each term, we have,

Thus, LHS ≠ RHS

Thus, the statement is false.

d)

Consider the Left hand side of the given statement,

Taking 4 common from each term, we have,

Thus, LHS = RHS

Thus, the statement is True.

Thus, Option (b) and (d) are correct.

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.
