The formula to this question is the amount of rows and how many fruit are in each row.
So 4x12=48
There are 48 apples in the apple orchard 
and 6x15=90
so 90+48=138
There are 138 pieces of fruit in total

Answer:

48 apple trees and 90 pears trees

Step-by-step explanation:

Number of rows of apple trees in an Orchard= 4 rows

Number of trees in each row= 12 trees

Total number of apple trees= Total number of rows × total number of trees

Total number of apple trees= 4×12

Total number of apple trees= 48 trees

Number of rows of pear trees in an Orchard= 6 rows

Number of trees in each row= 15 trees

Total number of apple trees= Total number of rows × total number of trees

Total number of apple trees= 6×15

Total number of apple trees= 90 trees

Hence, the correct answer is 48 apple trees and 90 pear trees or 138 tress

Factor each polynomial x^2-9x+10 <br> Show your work
jok3333 [9.3K]

Answer:

not factorable

Step-by-step explanation:

x^{2}  - 9x +10\\

The easiest way to factor is to find two numbers of the "a" value (the coefficient before x^{2}) and the factors of the c value (10) that ADD up to give you -9, in this case it would be:

1          -10  --> 1(-10) gives you -10

1           -1    --> 1(-1) gives you -1

adding these together -10 + (-1) = -11 which does not equal -9.

You could stop here and conclude that this is not factorable by inspection.

Another method: using the quadratic formula to find its roots.

Roots: (\frac{9-\sqrt{41} }{2}, 0) and (\frac{9+\sqrt{41}}{2}, 0)
