Answer:
98
Step-by-step explanation:
From the statement of similarity, we can write this proportion.
TV/MV = UV/LV
28/x = 16/56
16x = 28 × 56
x = 7 × 14
x = 98
OK. Then let's solve for ' r '. That means you have to come up with an equation that says r = everything else.
Step #1:
Write the equation you're given: <span>S = L (1 - r)
Let's divide each side by ' L ': S/L = 1 - r
Subtract 1 from each side : S/L - 1 = -r
Multiply each side by -1 : <em> 1 - S/L = r</em>
and there you have it.

Answer:
The team lost 13 yards
Step-by-step explanation:
They lose 20 then gain 7. so the equation would be 20-7=13
Here is the answer, with a picture of how you do it:)
X^2 +6x -5 = 0
x^2 +6x = 5 . . . . . add 5
x^2 +6x +9 = 14 . . . add 9
(x +3)^2 = 14 . . . . . . write left side as square
x +3 = ±√14 . . . . . . . take the square root
x = -3 ±√14 . . . . . . . subtract 3
Selection C is appropriate.
