Formula = (a + b)^2 = a^2 + 2ab + b^2
x^2 + 4x + 4 + 9 = 0
x^2 + 4x + 13 = 0
Answer: 19 but yes
Step-by-step explanation:
The sum of angles of all triangles is 180
Answer:
Step-by-step explanation:
<u>The coordinates of E and F are:</u>
<u>Find the slope:</u>
- m = (- 4 - 4)/(2 - 4) = - 8 / - 2 = 4
<u>Use point-slope form and point E:</u>
<u>Convert into slope-intercept form:</u>
- y = 4x - 16 + 4
- y = 4x - 12
The matching choice is C
Answer:
Step-by-step explanation:
So we have y-3=2(x+4)
So the first thing we want to do is distribute the 2 in front of the (x+4)
2(x+4) = 2x+8
Which means we have:
y-3=2x+8
Remember we need to get it into the form y=mx+b
As you can see here the 3 is preventing our equation from being in that form to we need to add it to both sides. This leaves us with:
y - 3 + 3 = 2x+8+3
Which gives: y = 2x+11
Therefore the slope form of this equation is y = 2x+11
