Factorise 6b²+3b+8b+5

(6b + 5)(b + 1).

Step-by-step explanation:

6b² + 3b + 8b + 5

= 6b^2 + 11b + 5

= 6b^2 + 6b + 5b + 5

= 6b(b + 1) + 5(b + 1)     b + 1 is common so:

= (6b + 5)(b + 1)

( 6b + 5 ) ( b + 1 )

Step-by-step explanation:

6b² + 3b + 8b + 5

6b²+ 11b + 5

6b²+ 5b + 6b + 5

( 6b + 5 ) ( b + 1 )

- 70

this is the answer for you hope it

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
