The volume of the cube would be S^3, where S is the length of the side.
Volume = (5a + 4b)^3
Which becomes:
(5a+4b)(5a+4b)(5a+4b)
Multiply the first two sets of parenthesis by each other:
(25a^2+40ab+16b^2)(5a+4b)
Now multiply that by the 3rd set of parenthesis to get:
125a^3+300a^2b + 240ab^2 + b^3
100m= 0.621371 miles
11 seconds = 0.0030556 hours
v=d/t
<span>0.0621371miles/0.0030556hour=20.3355miles/hour</span>
So with the significant digits the answer would be 20.3 miles/hour.
Therefore, this answer should be correct
do you go to k12???if so what grade
Answer:
x = 25
Step-by-step explanation:
The other angle in the triangle would equal 130 because the sum of angles in a triangle add up to 180.
2x + 130 = 180 because it is a linear pair
2x = 50
x = 25
Answer:
4.5 cm
Step-by-step explanation:
Circunference = 2π*radius = 2*3.14*radius = 6.28*radius = 28.26
so radius = 28.26/6.28 = 4.5 cm
Now I don’t know how to do this but I would recommended a tutor for you
