There are a total of 324 students enrolled in armstrong elementary school the girls our number the boys by 34 write an equation in standard form that represents the total number of students at armstrong elementary school use x to represent the number of girls and use y to represent the number of boys

2y+34=324

Step-by-step explanation:

Total=324

x=girls

y=boys

x+y=324

y+34+y=324

2y+34=323. required equation to represent total number of students in the school

- 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
