20x≥100

5 gallons needed to travel 100 miles
1/25
1/5 x 1/5 = 0.04 or 4/100
4/100 simplified is 1/25
10 x n +15 +11 x n
btw you know that x= the multiplication sign right.
Answer:
The area of rectangle is 12cm² and the perimeter is 14cm.
Step-by-step explanation:
First, you have to find the length of the rectangle using Pythagoras Theorem :
a² + b² = c²
a² + 3² = 5²
a² = 5² - 3²
a² = 16
a = √16
a = 4 cm
Next, you have to find the perimeter and area of rectangle :
Perimeter = 2(length + breadth)
P = 2(4 + 3)
P = 2(7)
P = 14 cm
Area = length×breadth
A = 4×3
A = 12 cm²
