Bạn tự vẽ hình nha ^^
Ta có điểm M nằm giữa 2 điểm I và K ( 2cm < 7cm ) , nên : 
IM + MK = IK 
=> 2 + 7 = IK 
=> IK = 9 cm 

Xin lỗi bạn nha , mình nhầm 

Gọi ƯCLN của 5a + 4 và 3a + 5 là m 
5a + 4 chia hết cho m <=> 15a + 12 chia hết cho m 
3a + 5 chia hết cho m <=> 15a + 25 chia hết cho m 
=> 15a + 12 - (15a + 25 ) chia hết cho m 
=> -13 chia hết cho m 
=> 5a + 4 và 3a + 5 không phải là 2 số nguyên tố cùng nhau

Chỉ có 1 đắp án như vậy 
=> B là đắp án đúng  


 

theo đl VI-ET: X1 + X2 =2 VÀ X1.X2 = m -8.

giải hệ phương trình : 3x1 -x2 = 0 và x1 +x2 =2

ta tìm được x1 =1/2     và x2 =3/2

thay x1 , x2 vào x1.x2 = m-8

=> m =35/4

X x 3 + X x 5  X x 7 ... + X x 101 = 31200

= X x ( 3+5+7 ... + 101)=31200

3+5+7...+101 = 2600

X = 31200 : 2600 = 12

X = 12
