First you multiply 4*n and n=3 so 4*3 = 12
then you have 9+12-1
9+12= 21
21-1=20
so your answer would be 20
Answer: The angles at each vertex of the rectangle are right angles
Step-by-step explanation:
Step-by-step explanation:
-6a - 4(a - 3) = -6a + 15
=> -6a - 4a + 12 + 6a - 15 = 0
=> -4a - 3 = 0
=> -4a = 3
=> a = -3/4
Answer:
y = -6x - 6
Step-by-step explanation:
<u>First, subtract 12x from both sides:</u>
12x + 2y = -12
-12x -12x
-----------------------
2y = -12x - 12
<u>Divide both sides by 2:</u>
y = -6x - 6
The answer is 16, good luck
