To find the height of the parallelogram you would divide 6 from the area, 27, to get the answer 4.5,
So h=4.5
For the first one, you're answer would be AC. since C is also a right angle, and angle A is hypnotenuse to C
Answer: (-3,4) and (9,20)
I think these two points will make the answer you have been looking for.
Addition: negative four plus negative four plus negative four equals negative twelve
Multiplication: negative four times three equals negative twelve
Division: twelve divided by 3 equals negative four
Our given inequality is:
-7x < -42
To solve for the inequality, we need to simplify for x and ensure we've carefully answered the question.
Currently, x is being multiplied by -7.
To get x by itself, we need to perform the opposite of what's being done.
Remember, what you do to one side of an equation/inequality, you must do to the other.
The opposite of multiplying is dividing.
Divide -7x by -7 to get x.
-7x / -7 = x
-42 / -7 = 6 (Dividing a negative by a negative makes a positive, the same goes with multiplying)
You're left with x < 6
When we divide/multiply by a negative, we need to flip the inequality with the opposite value.
Your final inequality is:
x _> 6
I hope this helps you. :)
