Answer: n=451
8*42+3*59-62=n
336+177-62=n
451=n

Answer:
35 slices originally
Step-by-step explanation:
1. 0.4 means 40%
2. if 14 slives equal 40% we need to divide by 4 to find 10%
3. 14 divided by 4 is 3.5
4. then we multiply 3.5 (10% of the cake) by 10 because 10•10=100(%)
3.5•10 equals 35 slices
A rate is a special ratio in which the two terms are in different units

Answer:
-3x^6 -x^4 +2x^3 -8x +8
Step-by-step explanation:
Use the distributive property 4 times.
(-3x^3 + 2x - 4)×(x^3 + x - 2)
= -3x^3(x^3 +x -2) +2x(x^3 +x -2) -4(x^3 +x -2) . . . . once
= -3x^6 -3x^4 +6x^3 +2x^4 +2x^2 -4x -4x^3 -4x +8 . . . . 3 more times
= -3x^6 +x^4(-3+2) +x^3(6 -4) +2x^2 +x(-4 -4) +8 . . . . group like terms
= -3x^6 -x^4 +2x^3 -8x +8
