I'm pretty sure it is 5:55
F(-5) = 2(-5) + 1 = -9
g(-5) = (-5)^2 = 25
(f*g)(-5) = -9(25) = -225
Answer:
So length of top of table is 3x-7 inches.
Step-by-step explanation:
Here we are given that the top of the table has a width that is given by 2x inches.
The area of the top is given by:

Now the top of the table is of the shape of rectangle and area of rectangle is given by:

where l is length of the table and w is width of the table.
Plugging the values of A and w in the formula we have:

Dividing by 2x,
l=3x-7 inches
So length of top of table is 3x-7 inches.
Answer:
1/2
Step-by-step explanation:
There are a total of 25 students. 3 don't study art or biology. 10 study only biology. 6 study both art and biology. This means the remaining students only study art.
1. Calculate the number of students taking art
only art: 25 - 3 - 6 - 10 = 6
number of students taking art and biology: 6
total number of students taking art: 12
2. Calculate the probability
Out of the 12 total students taking art, 6 are in art and biology.
6/12 = 1/2
