Answer: For this one its most likely Isoceles because only two sides are equal.
The perimeter is all sides length added together. You can make an equation:5+5+x+x where x is the length.
5+5=10 18-10=8 There is two sides so you do eight divided by two
The length is 4
Answer:
see below
Step-by-step explanation:
side opposite 90 angle = x 
sides opposite 45 angle = x
the multiplication and division by should be self explanatory
1. x = 5, y = 5
2. v = 10, u = 10
3. x = 
, y = 
4. m = 5, n = 
5. a = 
, b =
6. a = , b =
Answer:
y = 4
Step-by-step explanation:
distribute
10 + 2y = 18
minus 10 from both sides
2y = 8
divide by 2
y = 4
C. The 2 in the denominator turns into -2 and you just take the coefficients directly from the numerator.
