W equals 14/8 is the correct answer
f(x)=(x+4) ^2 −25
to solve set equal to zero
0 =(x+4) ^2 −25
add 25 to each side
25 = (x+4) ^2
take the square root of each side
square root (25) =(x+4)
+- 5 = (x+4)
5 = x+4 -5 = x+4
subtract 4 from each side
1 =x -9 =x
Answer:
12
Step-by-step explanation:
The range of a data set is just the difference between the largest and smallest values.
So, let's find the smallest value: it's 39. The largest value is 51.
Their difference is:
51 - 39 = 12
Thus, the answer is 12.

The shape is a trapezoid and its area formula is:
A =

h
a is a base length, b is another base length and h is the height.
A =

(10.8)
A = 81
So the area of the shape is 81yd²
.45*10^4=4500
