The correct answer is D. (3x - 4) (2x + 5)
Here's why:
6x2 + 15x - 8x - 20=
6x2 + 7x - 20
140 + 140 + 95 + 95 = 470 feet
Hope this helps!
Answer:
you can simplify rations just like you simplify fractions. Whenever you are able to evenly divide both parts of the ratio with out changing the equation's answer, you are able to.
for example
if it were 3:6, you can simplify this by dividing these both by 3, leaving you with 1:2.
The answer is 8km.
1:100,000 = 1.6 miles = 1 kilometer x 8 = 8 km
