Multiply: (5x − 2)(4x2 − 3x − 2)
Alex Ar [27]
Hello there!

(5x - 2)(4x² - 3x - 2)

Use the distributive property

=(5x)(4x²) + (5x)(-3x) + (5x)(-2) + (-2)(4x²) + (-2)(-3x)² + (-2)(-2)

= 20x³ - 15x² - 10x - 8x² + 6x + 4

= 20x³ - 23x² -4x + 4


As always, it is my pleasure to help students like you. Let me know if you have any questions.

Solve by substitution <br> 1. 6x+ 5y=7 x-y=3<br> 2. 3a +2b =4 2a + b=6<br> 3. 2x + y= 4 4x -y=2
Juli2301 [7.4K]

Answer:

1. y = 11

x = -48

2. a =8

b= -10

3. x= 1

y= 2

Step-by-step explanation:

1 . 6x + 5y = 7

x-y= 3

6x+5y = 7

6x-6y =18

-1y = - 11

6x + 5y = 7

y = 11

6x + 55 = 7

6x = -48

x = -48
