Answer: -4 (m + 6) = -8
We can use the distributive property for the first half of the equation.
-4 × m = -4m
-4 × 6 = -24
-4m - 24 = -8
Now we add 24 on bothe side sof the equation to get -4m by itself.
-4m - 24 + 24 = -8 + 24
Now we get -4m = 16
Divide -4 on both sides to get m by itself
-4m/-4 = 16/-4
Simplify and we get m = -4

Let us check series : -10 /-2 = 5 -50/-10 = 5
so it is a geometric series with a= -2 and r= 5
sum formula for n terms of geometric series = a ( r^n -1 ) /( r-1)
here we find S5 that is n= 5 = -2 ( 5^ 5 - 1) /( 5-1)
= -2 ( 3125 -1) / 4 = -1562
second series is : 1.5/1 = 1.5 2.25/1.5 = 1.5
this is also geometric series but n = 12 a= 1 and r= 1.5
we use same formula
S12 = 1 ( (1.5) ^12 -1) /( 1.5-1) =
128.74 / 0.5 = 257.49
Last is 2/1= 2 4/2 = 2 8/4 = 2 so r = 2 a = 1 and n = 12
we use same formula 1 ( 2^12 - 1) / (2-1)
= 4095

Answer:
A- Cai are used an invalid reason to justify the congruence of a pair of sides or angles.
Step-by-step explanation:
In step 4, Cai referred to the angles as "alternate interior." In fact, they are "corresponding." The reason used to justify congruence of the angles was invalid.
