Find each sum or difference by combining the parts that are alike.
a. 417+231 = hundreds + tens + ones + hundreds + tens + ones
= hundreds + tens + ones
b. (4x²+x+7)+(2x²+3x+1)
c. (3x³−x²+8)−(x3+5x2+4x−7)
d. 3(x³+8x)−2(x³+12)
e. (5−−²)+(+²)
f. (3p+1)+6(p−8)−(p+2)

a.  6 hundreds + 4 tens +8 ones

b. 6x² + 4x + 8

c. 2x³ - 6x² - 4x + 15

d. x³ + 24x -24

e. 5 + 8

f. 8p - 49

Step-by-step explanation:

a. 417 + 231 = 4 hundreds+ 1 tens + 7 ones + 2 hundreds + 3 tens + 1 ones = 6 hundreds + 4 tens +8 ones.

b. (4x² + x+ 7) + (2x² + 3x + 1) =6x² + 4x + 8

c. (3x³- x² +8) - (x³ + 5x²+ 4x - 7) =2x³ - 6x² - 4x + 15

d. 3(x³ + 8x) - 2(x³ + 12) = x³ + 24x -24

e. (5 - - ²) + (9 + ²) = 5 + 8

f. (3p + 1) + 6(p - 8) - (p + 2) = 8p - 49 (Answer)
