Answer: 11.2x -9.6
Step-by-step explanation:
7.2(x + 3) + 4(x - 3) - 12 - 7.2* (x + 3) + + 4*(x - 3) then
7.2x + 21.6 + 4x - 12 - Combining like terms 7.2x+ 4x and numbers + 21.6- 12
7.2x + 4x +21.6 -12 Then we have
11.2x -9.6
x^2 - 49 = 0
Add 49 to both sides:
x^2 = 49
Take the square root of both sides:
X = 7
Answer:
<h2>In the attachment</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
(x₁, y₁) - point
We have the equation:

Therefore we have
the slope m = -2/3
and the point (-9, 5)
A slope

rise = -2
run = 3
From the point (-9, 5) ⇒ 2 units down and 3 units to the right.
The hypotenuse is 20.59. 10^2+18^2=C^2
