Answer:

x=-1

Step-by-step explanation:

4(x−3)=8(x−1)

Distribute

4x - 12 = 8x -8

Subtract 4x

4x-12 -4x= 8x-8-4x

-12 = 4x-8

Add 8 to each side

-12+8 = 4x-8+8

-4 = 4x

Divide by 4

-4/4 = 4x/4

-1 =x

ABC is the middle line of MN in an equilateral triangle. If AB = 8 cm, then find the perimeter MBN.
qaws [65]

Answer:

the answer is 12

Step-by-step explanation:

since the triangle is equilateral meaning all side of ABC is equal to each other AB= BC = AC= 8cm and MN is the middle line that divides AB and BC by two

thus, MB =BN= 4 cm. MN is the middle line thus will also be equal to the half of AC  meaning MN=AC/2= 4cm. and perimeter  is MBN = MN+MB+BN= 4cm+4cm+4cm =12cm
