Answer:
35 is the length of BE
Step-by-step explanation:
2(2x + 5) = 8x - 50
4x + 10 = 8x -50
10+50 = 8x-4x
60= 4x
15 = x
2x + 5 = length of BE equal to length of DE
2(15) +5 = BE
30 +5
35 is the length of BE
Answer:c
15x - 4
Step-by-step explanation:
15x - 4
The table is missing in the question. The table is provided here :
Group 1 Group 2
34.86 64.14 mean
21.99 20.46 standard deviation
7 7 n
Solution :
a). The IV or independent variable = Group 1
The DV or the dependent variable = Group 2
b).


Therefore, 

t = -2.579143
Now, 
df = 7 - 1
= 6
Therefore the value of p :

= 0.020908803
The p value is 0.0209

So we reject the null hypothesis and conclude that 
3?
i’m not too sure sorry boo xxo
