We can write this expression as 10 - 4 = 9 - x
10 - 4 = 9 - x
6 = 9 - x
6 - 9 = 9 - x - 9
-3 = -x
-3/-1 = -x/-1
3 = x
Hope This Helped! Good Luck!
hi how you doing
BTW why do we have to click answer question to get to chat box
um hello?
how do you answer the thing
Answer:
- a) AB = 10 units
- b) Midpoint is (2, 6)
===================
<h3 /><h3>Given</h3>
- Points A( - 1, 10) and B(5, 2)
<h3>To find</h3>
- a) The length of AB
- b) The midpoint of AB
<h3>Solution</h3>
a) Use the distance formula:

Substitute the coordinates and calculate:

The distance is AB = 10 units
b) Use midpoint formula and find x and y- coordinates of this point:
and 
Substitute coordinates and find the midpoint:
and 
The midpoint is (2, 6)
4.6+4.5=9.1÷1.3=7
so expression is (4.6+4.5)÷1.3=7
Answer:
9a^2 + 42a + 49
Step-by-step explanation:
expand to (3a+7) (3a+7) then distribute then combine like terms
