Option B:
The relationship between angle j and angle k is j° + k° = 180°.
Solution:
Given JKLM is a parallelogram.
angle J and angle K are consecutive angles.
To find the relationship between angle j and angle k:
<em>In parallelogram, the sum of the consecutive angles is 180°.</em>
⇒ m∠J + m∠K = 180°
⇒ j° + k° = 180°
Hence the relationship between angle j and angle k is j° + k° = 180°.
Option B is the correct answer.
Hello,
Answer A: 2 has two pictures (values)
Answer:
C. the subtraction property of equality
Step-by-step explanation:
12-x = 7x + 32
Step - 1: -x = 7x + 20
In that case, we just swap 12 from the left side to right side, and then we subtract 12 from 32 which is on the right side. Therefore, we do not multiply, divide or add anything. So, the option "C" is correct.
Step 2: -8x = 20
In that case, we again subtract 12 by interchanging the side. Moreover, we change the side of 7x to deduct it from -x.
Therefore, in both the cases, we use the subtract property of equality.
This one is so easy that your brain refuses to accept it.
It's looking for a harder answer, but can't find it !
You're totally correct, as far you went. x² + 2x does = -1
Now add ' 1 ' to each side: x² + 2x + 1 = 0
Can you factor that quadratic ?
Can you mash it through the quadratic formula ?
Actually, it's the simplest possible perfect square.
x² + 2x + 1 = (x + 1)²
So the solutions of x² + 2x + 1 = 0 are both x = -1 .
Don't say anything.
I know it's embarrassing.
