That depends what the value of b is.
7 Brides for 7 Brothers
The ditloid 7 equals B for S B (7 = B for S B) means:7 = Brides for Seven Brothers
7 Brides for 7 Brothers.
6b-14=-7-b 6b+b =-7+14 7b =7 b =1
a = b/7
What is the answers to -7 ( a + b - 5 ) + 8 ( -3a +2b ) + b ( 7 + 3 )
b + b + b + 7 = 223b + 7 = 223b = 15b = 5
b^(2) + 8x + 7 Does NOT factor . Reason; you have two unknowns, viz. 'b' & 'x'. However, if you means b^(2) + 8b + 7 . Herewe have one unknown viz. 'b'. This factors to ( b + 7)(b + 1)
b^2 + 8b + 7 factors to (b + 7)(b + 1)
7
-1
b times 7
