3. (5n-6)(4n+7)

4. (2n=8)(8n+3)

5. (6x-4)(6x-8)

Answers

Answer 1
Answer: 1. (b-7)(2b-7) = 2b^(2) -21b +49; b = 42 => 2*41^(2) -21*42 + 49 =
3528 - 882 +  49 =  2695;
Answer 2
Answer:

Answer:

B = 42

A = 93  

N = 29

X = 36

1. 2695

(b - 7)(2b - 7)

(42 - 7)(2[42] - 7)

35 * (84 - 7)

35 * 77

2695

2. 168544

(4a - 4)(5a - 7)

(4[93] - 4)(5[93] - 7)

(372 - 4)(465 - 7)

368 * 458

168544

3. 17097

(5n - 6)(4n + 7) 29

(5[ 29] - 6)(4[ 29] + 7)

(145 - 6)(116 + 7)

139 * 123

17097

4. 15510

(2n = 8)(8n + 3)

ASSUMING THE = SHOULD BE PLUS

(2n + 8)(8n + 3)

(2[ 29] + 8)(8[ 29] + 3)

(58 + 8)(232 + 3)

66 * 235

15510

5. 44096

(6x - 4)(6x - 8)

(6[36] - 4)(6[36] - 8)

(216 - 4)(216 - 8)

212 * 208

44096
