Answer:
<h2>
B. (x-4)(x+i)(x-i) </h2>
Step-by-step explanation:
x³-4x²+x-4=
=x²(x-4)+(x-4)
=(x-4)(x²+1)
=(x+4)(x-i²)
<h3>=
(x-4)(x+i)(x-i) </h3>

QR=WS=2.93
RS=QW =2.04
QS=XR =2.28
RS=XQ=2.04
SY=QR =2.93
RY=QS =2.28
XY=XR+RY=2.28+2.28=4.56
XW=XQ+QW=2.04+2.04=4.08
WY=WS+SY=2.93+2.93=5.86
Perimeter of XYW=XW+WY+XY
Perimeter of XYW=4.08+5.86+4.56
Perimeter of XYW =14.5
Answer:
2/3
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points, then simplify:
(y2 - y1) / (x2 - x1)
(-1 + 7) / (4 + 5)
6/9
= 2/3
So, the slope of the line is 2/3
Answer:
x = -2, y = -3
Step-by-step explanation:
Solve for y:
If -3x + 9y = -21, and -3x +8y = -18, then -21 - y = -18
Add 18 to both sides:
-3 - y = 0, so y = -3
reconstruct new equation:
-3x + 9(-3) = -21, -3x + 8(-3) = -18
-3x + -27 = -21, -3x + -24 = -18
Using the new equation, solve for x:
add 24 to both sides of each equation :
-3x + -3 = 3, -3x = 6
x=<u>-2</u>
