X=3 pretty sure
Hope this helps!!
71° is the answer. 44°+27°=71°
a). (17º-17'-17") = 17<span><span>º + 17'/60 + 17"/3600 = </span>17.288055...</span><span>º

b) (18º: 8 + 23º: 4 - 8º)
18</span><span>º / 8 = 2.25</span><span>º

Yes...thats what u want to do. you want to get the x terms on one side and everything else on the other side.
8x = 7x + 3....so we will subtract 7x from both sides
8x - 7x = 7x - 7x + 3....simplify
1x, or just x = 3 (because ur 7x's cancelled each other out)
so ur answer is : x = 3
and u can check ur answer by subbing it back into the original equation.
8x = 7x + 3
8(3) = 7(3) + 3
24 = 21 + 3
24 = 24 (correct)
Answer:
4a²+3ab-a+a²
Step-by-step explanation:
So let's start off by simplifying this expression:
3a²-2ab+3b²-a+a²+5ab-3b²
Now let's subtract common terms XD
4a²+3ab-a+a²
