Correct option is b;
Step-by-step explanation:
Given equation 6x² + 11x + 4 = 0
Using factorization method to solve it
6x² + 8x + 3x + 4 = 0
Dividing the central term into two terms in such a way that their product gives 24x² and their sum gives 11x
taking common in the above equation
2x(3x+4) + 1(3x+4) = 0
taking 3x+4 common
(3x+4)(2x+1) = 0 --------------eq 1
we can write from eq1
(3x+4) = 0
3x = -4
and we can write from eq1
2x+1 = 0
2x = -1

Required: Determine the length of the straw
<em>Since the straw fits the diagonal of the box, the length of the straw is equivalent of the length of the diagonal.</em>
The length of the diagonal is calculated as:
Split
Hence, the straw length is:
Answer:
The ratio of surface areas is 36:121.
Step-by-step explanation:
We have, the ratio of the heights of two similar solids is 6:11. It is required to find the ratio of their surface areas. As the two solids are similar, it means that the ratio of surface areas of solids is directly proportional to the square of their heights such that,
So, the ratio of surface areas is 36:121.
