Given : the product of the numbers is 10, the sum of the squares of the numbers is 29, and the sum of the cubes of the numbers is 133.
Using identity and given details, we have to find the sum of two numbers.
Since, given that the product of the numbers is 10 that is
Also, given the sum of the squares of the numbers is 29 that is
and the sum of the cubes of the numbers is 133 that is
Using, the given identity ,
Substitute, the given values, we have,
Simplify , we get,
Divide both side by 19, we have,

The coffee shop used 52 pounds of Type A coffee.
Step-by-step explanation:
Cost of Type A coffee per pound = 5.25
Cost of Type B coffee per pound = 4.10
Total pounds used in blend = 142
Total cost = 642.00
Let,
x be the pounds of Type A coffee used
y be the pounds of Type B coffee used
According to given statement;
x+y=142 Eqn 1
5.25x+4.10y=642.00 Eqn 2
Multiplying Eqn 1 by 4.10
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 1.15
The coffee shop used 52 pounds of Type A coffee.
