Step-by-step explanation:

if the number is below 5, go down

if the number is 5 or above, go up

1,600 is closer to 2,000

1,483 is closer to 1,000

Then, 2000 > 1000

Factorise each of the following algebraic expressions completely,
LekaFEV [45]

Answer:

see explanation

Step-by-step explanation:

(a)

Given

2k - 6k² + 4k³ ← factor out 2k from each term

= 2k(1 - 3k + 2k²)

To factor the quadratic

Consider the factors of the product of the constant term ( 1) and the coefficient of the k² term (+ 2) which sum to give the coefficient of the k- term (- 3)

The factors are - 1 and - 2

Use these factors to split the k- term

1 - k - 2k + 2k² ( factor the first/second and third/fourth terms )

1(1 - k) - 2k(1 - k) ← factor out (1 - k) from each term

= (1 - k)(1 - 2k)

1 - 3k + 2k² = (1 - k)(1 - 2k) and

2k - 6k² + 4k³ = 2k(1 - k)(1 - 2k)

(b)

Given

2ax - 4ay + 3bx - 6by ( factor the first/second and third/fourth terms )

= 2a(x - 2y) + 3b(x - 2y) ← factor out (x - 2y) from each term

= (x - 2y)(2a + 3b)

I need help in the last one, i don understand it
Alex787 [66]

Answer:

84 = 7×12

84 = 3×4×7

84 = 2×2×3×7

Step-by-step explanation:

84 = 7 × 12 ( the factors of 12 are 3×4)

so 84 = 3×4×7 ( the factors of 4 are 2×2)

so 84 = 2x2x3x7

I hope it helps you!

Explain how you could use a number line to show that -4+3 and 3+(-4) have the same value.which property of addition states that
Anna007 [38]
For -4+3,
1. start with zero
2. move to left (-x axis) for 4 units (-4)
3. then move to right (+x axis) for 3 units (+3)

For 3+(-4)
1. Start with zero
2. Move the point to right side by 3 units (+3)
3. then move the point to the left by 4 units (-4)

For both you'll stop at -1.
