Answer:
A. Lynden used the distributive property 8X+8-2X-4=10-3X-6
Step-by-step explanation:
Lynden did the work properly.
Whitney misapplied the distributive property computing -2(x+2). She failed to apply the minus sign to the product of -2 and 2.
David failed to understand the order of operations: multiplication comes before addition, so the product -3( ) needs to be computed before any addition involving 10.
Answer:
The other measurement has to be 120 degrees. In other words, the two angles have to add up to 180 degrees. The method for that is same side interior.
Step-by-step explanation:
In same side interior angles, the sum of the two angles has to be 180 degrees. So we know that one of the angles is 60 degrees so we do 180-60=120.
