Answer:
w = 3
l = 10
Step-by-step explanation:
l = 4w-2
P = 26cm
P = (l + w) × 2
26 = (4w-2+w) ×2
26 = (4w + w - 2) × 2
26 = ( 5w - 2 ) × 2
26 ÷ 2 = 5w -2
13 = 5w - 2
13 + 2 = 5w
15 = 5w
w = 3
l = 4w - 2
l = (4 × 3) -2
l = 12 - 2
l = 10
Answer:
2
Step-by-step explanation:

First, simplify the top and bottom separately:

Then, just divide:

Independent is the gasoline amount and dependent is the mileage driven
Answer:
13 cm
Step-by-step explanation:
Using Pythagorean theorem
5²+12²=c²
25+144=c²
169=c²
In order to get rid of the ² it has to be square rooted
√169=√c²
c = 13
Its 80 because if you find perfect square around the number 80 you'd get
√64 and √81
which would be 8 and 9
