Find the unit rate. He drove 168 miles in 4 hours.
168/4= 42
He drives 42 Mph.
Multiply that by 7.
42*7= 294
He drives 294 in 7 hours.
I hope this helps!

Answer:
Uhhh, it can be factored into 3 * ( 3r - 1 )
Step-by-step explanation:
I think you know how factoring works. Other than that, I see no way fo proving that it can't be factored.
Answer:
16cm by 5cm
Step-by-step explanation:
P=2(l+w)
A= wl
80 factorization: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
you then would have to find 2 numbers that would add up to make 42.
When you try 16*2+5*2= 32+10= 42 cm as your perimeter.
16*5= 80 cm^2 as your area.
You can use the ASA postulate which means angle side angle. if 2 angles and the including side are congruent to the corresponding parts of another triangle then the triangles are congruent. hope that helps :)
