Answer:
<u>6b - 4a + 22 units</u>
Step-by-step explanation:
Perimeter = 2(length + width)
= 2(3b - 4a + 5 + 6 + 2a)
= 2(3b - 2a + 11)
= <u>6b - 4a + 22 units</u>
Answer:
x<1
Step-by-step explanation:
A^2 + 2AB + B^2 = (A + B)^2 ==>
16X^2 + 40X + 25 =
= (4X)^2 + 2*4*5X + 5^2 =
= (4X + 5)^2

The traveling time would be 470,588.235294km/hr
