efetue as operaçoes !!!
A)2a+4a+6a+8a+10a = 30a
B)5ab+5b+18ab-15,5ab = (5ab+18ab-15,5ab) +5b = 7,5ab + 5b =
5b(1,5a +1)
C)4a+5b+7a+8ab-9a-10b = (4a+7a-9a) +(5b-10b)+8ab
2a +(-5b) +8ab = 2a-5b+8ab = 2a(1+4b)-5b
D)3x²+4x²-7+5x-17= 7x² +5x-24
A)2a+4a+6a+8a+10a = 30a
B)5ab+5b+18ab-15,5ab = (5ab+18ab-15,5ab) +5b = 7,5ab + 5b =
5b(1,5a +1)
C)4a+5b+7a+8ab-9a-10b = (4a+7a-9a) +(5b-10b)+8ab
2a +(-5b) +8ab = 2a-5b+8ab = 2a(1+4b)-5b
D)3x²+4x²-7+5x-17= 7x² +5x-24
