Answer:
yes they are congruent because they have the same size and shape
Step-by-step explanation:
Variables: x, x+2, x+4 (that way, they're odd)
x+x+2+x+4 = 429
3x+6=429
3x=423
x=141
141, 143, 145
The biggest is 145 (141+4)
We presume you want to find values of x that make this true.
Subtract the right side and factor:
Once you have factors whose product is zero, you can find the values of x that make those factors zero. A product can only be zero if one or more contributing factors is zero.
To solve 2x-5=0, you can add 5 then divide by 2:
... 2x -5 = 0
... 2x = 5
... x = 5/2
