Given: isoceles ΔABC, median BD to base AC Prove: ΔADB≅ΔCDB

AB=CB    Def of isosceles triangle

AD=CD    Def of median

BD=BD    Reflexive property

ADBcongCDB  SSS congruency

Step-by-step explanation:

Statemet 1 AB=CB

Statement 2 AD=DC.

Statement 3 BD=BD.

Statement 4 Triangle ABD is congruent to triangle

CBD.

Reasons

Reason 2 Definition of Median

Reason 4 SSS

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?
