Answer:
A) AA postulate; 18
Step-by-step explanation:
Due to the similar triangles, we can set up the proportion and solve for x
8/(8+4) = 12/x
8/12 = 12/x
8*x = 12*12 ... cross multiply
8x = 144
x = 144/8
x = 18
As a decimal it is 0.2285714
THE NUMBERS AFTER THE DECIMAL NEED A LINE OVER THEM. They keep repeating themselves. Have a good one babes.
6 (7 n - 5 m) + 8 m
6 (7 n - 5 m) = 42 n - 30 m:
42 n - 30 m + 8 m
Grouping like terms, -30 m + 42 n + 8 m = 42 n + (8 m - 30 m):
42 n + (8 m - 30 m)
8 m - 30 m = -22 m:
42 n + -22 m
Factor 2 out of 42 n - 22 m:
Answer: 2 (21 n - 11 m)
Answer:
The answer is (4,-2)
Step-by-step explanation:
y=x-6
3x+2y=8
3x+2(x-6)=8
3x+2x-12=8 Combine like terms
3x+2x-12+12=8+12 add 12 to both sides then combine
5x=20→ x=4
then plug it in to y=x-6→y=4-6→y=-2
