2a-3+4b-2a-b-2a-b-3+5 Can be simplified to: 3b-1
9a +8 -2a -3 -5a = 2a +5
(6a3 - 19a2 + 15a)/(2a - 3) = a(6a2 - 19a + 15)/(2a - 3) = a(2a - 3)(3a -5)/(2a -3) = a(3a - 5)
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
2a-3+4b-2a-b-3+5=3b-1
2a-3+4b-2a-b-2a-b-3+5 Can be simplified to: 3b-1
9a +8 -2a -3 -5a = 2a +5
(6a3 - 19a2 + 15a)/(2a - 3) = a(6a2 - 19a + 15)/(2a - 3) = a(2a - 3)(3a -5)/(2a -3) = a(3a - 5)
9a +8 -2a -3 -5a = 2a +5
If 3a+5=5a+3, then: 3a+5 - 3a = 5a+3 - 3a 5=2a+3 5 - 3=2a+3 - 3 2=2a a=1
9a +8 -2a -3 -5a = 2a +5
2a+5a=3 7a=3 a=3/7 or .4286
3b -1
(a - 5)(a + 3) = a2 - 2a - 15
It is: (2*3)+5 = 11
The question already has the answer. If the area is 3, then you've already answered the question.If you meant the triangle had a base of 5 and a height of 3:A = base * height / 2A = 3 * 5 / 2A = 15 / 2A = 7.5
