7c^2d^2-14cd
Hope this helps a bunch!!!!!!!!!!!!
I am not sure if I am correct.
I think that the angles did not help to solve the problem, ( it makes an obtuse angle)
and the unit rate is 421 mph and 384 mph.
2*421+384*2= 1610 miles
or
2 (421+384)= 1610 miles
Answer: 1610 miles
The solution to the inequality expression is x ≥ - 5
<h3>Inequality expressions</h3>
Inequality are expressions not separated by an equal sign. Given the inequality;
–4(x + 3) ≤ –2 – 2x
Expand
-4x - 12 ≤ -2 - 2x
Collect the like terms
-4x + 2x ≤ -2 + 12
-2x ≤ 10
Divide both sides by -2
-2x/-2 ≤ 10/-2
x ≥ - 5
Hence the solution to the inequality expression is x ≥ - 5

You have to add 75 to Both sides and 50+75= 125
So q=125. Hope this helped!
