Evaluate Blue when z = 9
To do this, we simply substitute 9 for z in 

Convert indices to fraction


<em>Hence, the blue section has an area of </em>
<em></em>
The expression equivalent to the total distance Rhonda drove is 51x = 275
Given:
Distance 1:
Number of miles = 51 miles
Number of hours = 5 hours
Distance 2:
Number of miles = 55 miles
Number of hours = x hours
<em>Ratio of miles to number of hours</em> = 51 miles : 5 hours
<em>Ratio of miles to number of hours</em> = 55 miles : x hours
Equate the ratios
51 : 5 = 55 : x
51/5 = 55/x
cross product
51 × x = 5 × 55
51x = 275
x = 275 / 51
x = 5.392156862745098
Approximately,
x = 5.4 hours
Therefore, the number of hours taken to travel 55 miles is 5.4 hours

I think the answer is D but i could be wrong
To answer the question, simplify the polynomial by adding those that has the same degree of variable,
6 - 3x + (6x³ - 2x³)
6 - 3x + 4x³
Rearrange the polynomial with decreasing exponent or x,
4x³ - 3x + 6
This is a third-degree polynomial.
Angles B and D are congruent so:
(360-112-74)/2=87°
