Answer:
2 hours * (47 miles / hour) = 94 miles
multiply the value in miles per hour by the conversion factor '1.609344'.
So, 2.2 miles per hour = 2.2 × 1.609344 = 3.5405568 kilometers per hour.
Step-by-step explanation:
Answer:
120 cm^2.
Step-by-step explanation:
The area of one triangle = 1/2 * base * height
= 1/2 * 8 * 6
= 1/2 * 48
= 24 cm^2
So area of the pentagon = 5 * 24
= 120 cm^2.

Answer:
the second option and x=20
Answer:
Step-by-step explanation:
12a)To rationalize the denominator, multiply the denominator and numerator by √5.
b) (a+b)² = a² + 2ab + b²
(1 +√3)² = 1² + 2*1*√3 + (√3)²
= 1 + 2√3 + 3
= 4 + 2√3
a = 4 ; b =2
13) (a + b)(a - b) = a² - b²
