Answer:the length 7
Step-by-step explanation:each one is times 3 6x3 8x3 3x7=21
Even numbers are divided by two
Even numbers are easier to cope with in math problems
There are only odd prime numbers
You’ll distribute the 7 from (x-4) so your equation will be
28-x>_ 7x-28
then you’ll combine like terms (-x and 7x and 28 and -28
-56>_ -8x
divide by -8 on both sides and flip your sign
you’re answer is x<_7
x is less then or equal to 7
Well, there's many equations that represent real world situations. These equations we use a lot in engineering. For example, something fundamental is that we can calculate the velocity of something by knowing it's acceleration by taking the integral of the acceleration.
