Answer :
1. (b-7)(2b-7) = 2[tex] b^{2} [/tex] -21b +49; b = 42 => 2*[tex] 41^{2} [/tex] -21*42 + 49 =
3528 - 882 + 49 = 2695;
3528 - 882 + 49 = 2695;
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
