Henry bought 1/4 pounds of screws and 2/5 of backstop build a skateboard ramp. what is the total weight of the screws and nails

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

loloo

step-by-step explanation:

lololool

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

12 dolars one is cheaper becasue 3 pairs is 6 means is sock is 2 while the 12 is cheaper
