2(h + 3) = 2h + 6
because the number are the same /example2 times 3 equals 6. 3 times 2 equals 6
8(x + 2/3) = 8x + 16/3
To find two times the sum of ( x^2 ) and ( y^2 ) increased by three times the sum of ( x^2 ) and ( y^2 ), we first express it mathematically. The sum of ( x^2 ) and ( y^2 ) is ( x^2 + y^2 ). Thus, two times this sum is ( 2(x^2 + y^2) ), and three times it is ( 3(x^2 + y^2) ). Adding these together gives ( 2(x^2 + y^2) + 3(x^2 + y^2) = 5(x^2 + y^2) ).

The sum of xy times 3 is equal to 3(xy).
the sum of 3 times m and n
To find the least sum of money that 24, 30, and 54 will divide exactly, we need to calculate the least common multiple (LCM) of these numbers. The prime factorization of each number is: 24 = (2^3 \times 3), 30 = (2 \times 3 \times 5), and 54 = (2 \times 3^3). The LCM is obtained by taking the highest power of each prime: (2^3), (3^3), and (5^1). Thus, the LCM is (2^3 \times 3^3 \times 5 = 8 \times 27 \times 5 = 1080). Therefore, the least sum of money is 1080.
