Answer:
x² + 2ax + a² + 5x + 5a + 4
Step-by-step explanation:
Formula -
( a + b )² = a² + 2ab + b²
Steps -
( x + a )² + 5 ( x + a ) + 4
x² +2ax + a² + 5 ( x + a ) + 4
x² + 2ax + a² + 5x + 5a + 4
Answer:-3
Step-by-step explanation:
m=y2 - y1
m= x2-x1
-4= y1
2=y2
2--4=6
x2=6
x1=8
6-8=-2
6/-2=-3
<u>Slope is -3!!</u>

Answer:
945*134= 126630
Step-by-step explanation:
Answer:
L=10.326cm
P=31.30cm
Step-by-step explanation:
A=55=L*W
L=5+W
A = (5+W)(W) = 55
55=W^2 + 5W
0 = W^2 + 5W - 55
use quadratic formula
W = [-5 (+/-) sqrt(25-4(-55))]/2
W= 5.326 cm or W=-20.65, so W=5.326cm
L=5+5.326
=10.326cm
P=2W+2L
P=2(5.326) + 2(10.326)
=31.30 centimeters
