Answer:
Step-by-step explanation:
1 hour = 3600 seconds
Distance traveled in 90 seconds = 5 feet
Distance traveled in 1 second = 5/90
Distance traveled in 3600 seconds = 5*3600 / 90
= 5 * 40 = 200 feet
Answer:
x = 14
Step-by-step explanation:
I don't know which one you are supposed to solve it by so I will do both.
Solution by Cross Multiplication
For the equation
7x=24
The cross product is
7×4=x×2
Solving for x
x=7×42
and reducing
x=14
Solution by Proportion
Since the equation is an equality
If
7 ÷ 2 = 3.5
Then it is true that
x ÷ 4 = 3.5
Solving for x
x = 4 × 3.5
x = 14
Answer:
9x^4+3x^2 -6
Step-by-step explanation:
(3x^2-2)(3x^2+3)
expand to remove the bracket
9x^4 + 9x^2 -6x^2 - 6
9x^4 + 3x^2- 6
Answer:
it would be 457.2 cm or if you want it simplified then it would be 457 cm
hope this helped :)
No they are not equivalent
