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:
i recommend using something like reverse pythagreom theorm
Step-by-step explanation:
like so a^2 would usually be the long line but in this case its x so then try c^2 - b^2
in doing so you will get 225 - 81 sub that and you will get 144 the square root of that is 12 so then x would be 12
