Sand to cement
7:3
210:x
ask yourself what number is needed to multiply by 7 to get 210 ( so you'd divide 210 by 7 which is 30). Multiply the other side by thirty as well to get the value of x
3*30 which is 90
The answer to this question is true
Rectangle Area = length • width
5x • (x + 2) = area
(5x^2 + 10x) is the area, with no further ways to simplify.
4.5 meters = in 9 seconds
1 meter = 9/4.5 = 2seconds
so, a bee flys 1 meter in 2 seconds.
