Answer:
2p+3>2(p−3)
Use the distributive property to multiply 2 by p−3.
2p+3>2p−6
Subtract 2p from both sides.
2p+3−2p>−6
Combine 2p and −2p to get 0.
-3>6
This is true for any p.
p∈R

Answer:
x>2
Step-by-step explanation:
Set it up 180=(7x+10)+ z because angle b is on the flat line and then solve for x (180-10, then 170/7) and you’ll get the value of x and from there you can put it in all
Mn - 4m - 5n + 20
In this, mn and -4m have a common factor; m. So we can take that out to make it:
m(n-4) -5n + 20
Now, -5n + 20 also has a common factor which is 5, because 20/5 gives you 4, and 5/5 equals 1. So we can talk out that -5 (it doesn't need to be negative, but negatives on variable, no gusta). So you'd get
m(n-4)-5(n-4) OR m(n-4)+5(-n+4)
Answer:
Step-by-step explanation:
Given
x - 
= 9 ← square both sides
(x - )² = 9²
x² - 2 + 
= 81 ( add 2 to both sides )
x² + = 83
Now
(x + )² = x² + + 2, thus
x² + = 83 + 2 = 85
(x + )²= 85 ( take the square root of both sides)
x + =
