Answer :

1. Choose A, 2. Choose B, 3. Choose C, 4. Choose A, 5. Choose A

Explanation :

1. 91, 85, __, 73, __, 61

We see that each number has a difference of 6. Therefore, 91 minus 6 is 85. 85 minus 6 is 79, 79 minus 6 is 73, 73 minus 6 is 67, 67 minus 6 is 61.

Therefore, the missing numbers are :

91, 85, 79, 73, 67, 61

So, choose A.

2. 38, 46, __, 62, __, 78

We see that each number has a difference of 8. So, 38 plus 8 is 46, 46 plus 8 is 54, 54 plus 8 is 62, 62 plus 8 is 70, 70 plus 8 is 78.

Therefore, the missing numbers are :

38, 46, 54, 62, 70, 78

So, choose B

3. 34, 39, __, __, 54, 59

We see that each number has a difference of 5. So, 34 plus 5 is 39, 39 plus 5 is 44, 44 plus 5 is 49, 49 plus 5 is 54, 54 plus 5 is 59.

Therefore, the missing numbers are :

34, 39, 44, 49, 54, 59

So, choose C

4. 15, 30, __, 60, __.

We see that each number has a difference of 15. So, 15 plus 15 is 30, 30 plus 15 is 45, 45 plus 15 is 60, 60 plus 15 is 75.

Therefore, the missing numbers are :

15, 30, 45, 60, 75.

So, choose A.

5. 829 x __ = 829

∴ 829 x 1 = 829

So, choose A.

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

$4x^2-0x-9$

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

$4x^2-0x-9$

$=4x^2-6x+6x-9\\\\=2x(2x-3)+3(2x-3)\\\\=(2x+3)(2x-3)\\\\=(2x-3)(2x+3)$

therefore, the correct factorization of $4x^2-0x-9$ is (2x-3)(2x+3).
