Fractions and decimals are related in a very close way. Ways such as they are both representing a whole number.
for example
1/2 , 0.5 , 50%
all three numbers have the same value but are expressed in a different format. all three represent the same whole number.
another example would be
1/4 , 0.25 , 25%
hopefully this helped. and or makes sense.
LET ME KNOW :p
Answer:
Step-by-step explanation:
Area = 42x + 56
length * width = 14* 3x + 14*4
14 * width = 14*(3x+4)

The launchers height above the ground at zero distance h(x)+0+0+.4= 4 meaning that the height is 4 <span />

This is the equation we would use for this problem.
Now when we cross multiply, we get:
35(600)=100x
Simplify:
21000=100x
Divide each side by 100 to get x b itself:
210=x
So, as you can see, 210 is 35% of 600
The best math that i think you should take would be calculus.
