Answer:
Step-by-step explanation:
A more complicated expression such as 64x3+27y3 64 x 3 + 27 y 3 is also a sum of cubes since 64x3=(4x)3 64 x 3 = ( 4 x ) 3 and 27y3=(3y)3 27 y 3 = ( 3 y ) 3 . Please note, that expressions such as 2x3 2 x 3 are not perfect cubes.
Step-by-step explanation:
this is answer

It would be 3 minutes for a dollar
For this case we must indicate the value of the following expression, expressed in scientific notation:
We have that for multiplication properties of powers of the same base, the same base is placed and the exponents are added:
Then, rewriting the expression we have:
Answer:
Ok so since the ratio is 7:5 that means you have an 8'' sandwich with 12 (7+5) separate units. imagine drawing the sandwich and dividing it into 12 sections.
so 8/12= .6666666 (thats the length of 1 unit)
now take .6666666 x 7 units = 4.6666666 inches '' (thats the bigger half)now take .6666666 x 5 units = 3.333333333 inches (thats the shorter half)
you'll notice that 4.66666666'' + 3.3333333" = 8''
