Here’s the correct answer, how I got it, how to help for next time, and the equation graphed :)
Answer: he set the factored expressions equal to each other
Step-by-step explanation:
Answer:
A ) Distributive property, subtraction property of equality, subtraction property of equality, division property of equality.
Step-by-step explanation:
The given equation:
4 ( x + 5 ) = 2 x + 2
4 x + 20 = 2 x + 2 ( Distributive property ),
because: 4 · x + 4 · 5 = 4 x + 20
Then follows : 4 x - 2 x + 20 = 2 x - 2 x + 2 ( Subtraction property of equality )
2 x + 20 = 2
After that:
2 x + 20 - 20 = 2 - 20 ( Subtraction property of equality )
2 x = - 18
Finally:
x = - 18 : 2 ( Division property of equality )
x = - 9
Answer:
n=11
Step-by-step explanation:
This is a right angle, so the angles are complementary and have a sum of 90°.
