The sum of the squares of two numbers is four less than the sum of one hundred plus half a hundred What are the two numbers?
The two numbers are five and eleven. 5*5=25 and 11*11=121 and 25+121=146 which is four less than 100+50 which is 150.
-5 x - 20?
-25
Why the square of the sum of two numbers is different from the sum of the squares of two numbers?
call the numbers a & b (a+b)2 = a2+2ab+b2 which is greater than a2 + b2 by twice the product of the numbers. Check: say 3 and 5 32 + 52 = 9 + 25 = 34 (3 +5)2 = 64, greater by twice a x b. QED -------------------- If a and b are the numbers, then (a+b)2 = a2 + 2ab + b2, which is different from a2 + b2 (not necessarily larger). The two quantities are equal only when one (or both) of a,b is zero.
How many three digit whole numbers have digits that sum to 25?
The first digit must be 7 or greater, because the digits of 699 only sum to 24. Of the numbers beginning with 7, only 799 sums to 25, because if either of the other two digits are less than 9, the sum will be less than 25. That's one so far. For number beginning with 8, the other two digits must sum to 17. That means they must be 9 and 8. So there are two suitable numbers beginning with 8, namely 889 and 898. That's a total of three so far. Finally, we have numbers beginning with 9. The other two digits must sum to 16, so the candidates are: 9 and 7, or 8 and 8. That gives us three numbers that fit the bill: 997, 979 and 988. That's six altogether. So the answer is six.
What is the difference between the product of 20 and 5 and the sum of 20 and 5?
20x5 =100 20+5=25 100+25= 125
Two numbers have a sum of 25 and a product of 154 what are the numbers?
14 and 11
What are the numbers if the sum of two numbers is 31 and the product is 150?
25 and 6.
What number is the product of the same two odd numbers and sum to 7?
No two odd numbers can sum to 7.
What are the two numbers that have a sum of 25 and a product of 150?
10 and 15
The sum of 2 numbers is 25 and their product is 156 What are the numbers?
If the sum of 2 numbers is 25 and their product is 156, the numbers are 12 and 13.
A sum of 33 and a product of 200?
The two numbers with a sum of 33 and a product of 200 are 25 and 8. 25 x 8 = 200, 25 + 8 = 33.
The sum of 2 numbers is 25 and their product is 156 What are the numbers-?
If the sum of 2 numbers is 25 and their product is 156, the 2 numbers would be 12 and 13.
The sum of these numbers is 28 and the product is 75 what are the numbers?
25 + 3 = 28 25 x 3 = 75 The two numbers are therefore 25 and 3.
Given two real numbers whose sum is ten What is their maximum product?
5+5 = 10 (Sum is ten)5*5 = 25 (Product is 25)*this product is maximum for all any 2 real numbers that == 10
What two multiply numbers equal the sum of 100?
It's unclear whether you want two numbers that add to a sum or multiply to a product. 25 x 4 = 100 25 + 75 = 100
What is two numbers whose product is 75 and sum is 28?
25 and 3 25*3 = 75 25+3 = 28
If the sum of two numbers is 7 and there product is 25 what is the sum of there reciprocals?
Suppose the two numbers are x and y. Then, the sum of THEIR reciprocals is 1/x + 1/y = y/xy + x/xy = (y + x)/xy = 7/25
