Answer: 428
Step-by-step explanation:
This is a substitution problems,
Just substitute for the values of x and y , multiply them out and add.
Here we go;
5x³ + 4y³
= 5(4³) + 4(3³)
= 5( 4 x 4 x 4 ) + 4( 3 x 3 x 3)
= 5 x 64 + 4 x 27
= 320 + 108 add directly or find the common factor
= 4(80 + 27)
= 4(107)
= 4 x 107
= 428
Answer:
The geometric mean between 4 and 9 is 6.
Find ing the common denominator would make it 10.
for 1/2 to get to 10 you have to multiply by 5
1/2x5= 5/10
then you have to convert 2/5 to get the denominator to be 10
so you multiply 2/5 by 2
2/5x2= 4/10
5/10 is greater than 4/10
Well say for example that you have two numbers such as 3 and 6, and you try to do the least common multiple i would assume it would look like
3 6 9
6 12 18
if one number is a multiple of the other then it is automatically the least common multiple. In this example the least common multiple is 6. If this does not suffice or make sense then please comment and try to make your question more clear so i can help you.
