9(2j + 7 + 5j). Use either the commutative property or combine like terms to create an equivalent expression.

your answer is 63j+63.

Step-by-step explanation:

as i said before, this is your answer.

step 1: collect like terms. (add 7j and 5j because they are like terms.)

9(2j+7+5j)

9(7j+7)

step 2: distribute. (distribute the 9 to both your 7j and 7.)

9(7j+7) =

63j+63

i hope this helped

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
