X²+3x-28=0
(x+1.5)² - 1.5² - 28 = 0
(x+1.5)² - 25.75 = 0
(x+1.5)² = 25.75
Note: The answer is not listed on the option given. Maybe worth checking the if the original equation has been copied correctly.
Note: Consider x be the breadth of the box.
Given:
The surface area of the box is 204.25 square feet.
Length of the box = 10 ft
Breadth of the box = x ft
Height of the box = 6.5 ft
To find:
The value of x.
Solution:
The surface area of a cuboid is:
Where, l is length, b is breadth and h is height of the cuboid.
Putting 
in the above formula, we get
Using distributive property, we get
Divide both sides by 33.
Therefore, the correct option is B.
S=4LW+2WH
160=4(9)(4)+2(4)H
160 = 144 + 8H
160-144 = 144 - 144+8H
16 =8H
16/8H = 8H/8
H=2

Answer: 30 mins.
Step-by-step explanation:
The mode is the value that appears the most times.
In such a situation, first order the numbers in an ascending order:
15, 20, 25, 25, 30, 30, 30, 35, 35, 40, 45
As can be seen from the above, 30 is the number that appears the most so the mode is 30 mins.
