Answer: 548.8 square inches
Step-by-step explanation:
From the question, we are informed that a cereal box has a surface area of 280 square inches.
The surface area of a similar box that is larger by a scale factor of 1.4 will be gotten by multiplying 280 by the scale factor's square. This will be:
= 280 × (1.4)²
= 280 × 1.96
= 548.8 square inches
Given:
In a two-digit number, the tens digit is 5 less than the units digit.
The number itself is five more than three times the sum of its digits.
To find:
The number.
Solution:
Let the two digit number is ab. So,

Tens digit is 5 less than the units digit.
...(i)
The number itself is five more than three times the sum of its digits.



...(ii)
Using (i) and (ii), we get





Putting b=8 in (i), we get


Therefore, the required number is 38.
Answer:
A. the number 2 is a root of F(x) = 3x^2 - 11x +10
D. (x-2) is a factor of 3x^2 - 11x +10
E. (3x^2 - 11x + 10) / (x - 2) = (3x - 5)
