Convert 3 yards to inches.
1 yard = 36 inches
3 * 36 = 108
Now subtract this from Jason's jump:
108 - 98 = 10
So Doug's jump was 10 inches longer than Jason's jump.
Answer:

Step-by-step explanation:
For a negative exponent you always flip the number so instead of
it would be
and 5 to the first power is 5
Now for
any exponent with a zero it always equals 1
So 
Hope this helps!
Yes pretty much. It is very helpful with homework and school problems. Please give brainliest.
Answer:
Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
Step-by-step explanation:
i) f(x) = -(x+9)(x-21)
ii) therefore y = f(x) = -
+ 12x + 189 = - (
- 12x +36) + 36 + 189
iii) therefore y = f(x) = -
+ 225
iv) when x = 6 then y = 255
Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
Total sq units of dotted rectangle = 3*5=15sq units
Shaded area= 15-(3*4*1/2+2*5*1/2)
=15-(6+5)
= 15-11
= 4 sq units
