That would be D. Adjacent because they share a side.
Answer:
x = -4
y = -21
Step-by-step explanation:
To solve this, we will need to set up a system of equations and get rid of a variable.
-3x - 2y = 54
-6x + 2y = -18
From this, we can see that the 'y' variables can be cancelled out if we add the two together. This means that we must add these equations to each other to cancel out the 'y' variables:
-3x - 2y = 54
-6x + 2y = -18
-------------------- +
-9x = 36
x = -4
Since we have solved for 'x', we can simply plug this value into an equation to find 'y'.
-3(-4) -2y = 54
12 - 2y = 54
-2y = 42
y = -21.
Answer: 4 units! Just took the test!
Step-by-step explanation:
Answer:
150 cm²
Step-by-step explanation:
Since the room is square, assuming that it is a cube, the area will be 6s², where s is the side length.
Given a side length of 5cm, the area is
6(5)² = 6cm × 25cm = 150cm²
7x - 1 + 6x - 1 = 180
13x - 2 = 180
13x = 182
x = 14
