So lets ABCD are the sides of the square and AB=CD, AC=BD and the Angle ABC = 90 so therefore by making a diagonal we can use the SAS or SSS congruency for two triangles, so we can prove two triangles are equal and that is why the shape is square.
Answer:
50
Step-by-step explanation:
must use PEMDAS (order of operations)
step 1: multiply 7 and 6
8 + 42 / 3 x 3
step 2: divide 42 by 3
8 + 14 x 3
step 3: multiply 14 and 3
8 + 42
Add to get 50
Answer:
n=-1, 1
Step-by-step explanation:
-4|8n|=-32
Divide each side by -4
-4|8n|/-4=-32/-4
|8n|=8
When we have absolute values, we need to make two equations, one positive and one negative
8n=8 8n=-8
Divide each side by 8
8n/8 = 8/8 8n/8 = -8/8
n=1 n=-1
