Just completed round or to the tenth etc
Answer:
-4 <u>+</u> 2*sqrt(5)
Step-by-step explanation:
2x^2+16x-8=0
Factor out the 2: 2(x^2+8x)-8=0
Add (b/2)^2 = (8/2)^2 = 16
2(x^2+8x+16)-8 = 0 + 2*16
2(x+4)^2=40
(x+4)^2=20
x+4=<u>+</u>sqrt(20)
x=-4<u>+</u>sqrt(20) = -4 <u>+</u> 2*sqrt(5)
Answer:
-x -9y
Step-by-step explanation:
-(3x+y)+2(x-4y)
-3x -y +2x -2*4y
-x -y -8y
-x -9y
If this was algebra then the answer would be : the equation because there are no like terms.
Answer:
d = 11 units if rounded to nearest whole number
Step-by-step explanation:
Distance formula:
d=√((x_2-x_1)²+(y_2-y_1)²)
Your ordered pairs (-1, 1) and (4, 11)
d=√((4-(-1))²+(11-1)²)
d=√((4+1))²+(10))²)
d=√((5)²+ 100)
d = √125
d = 11.18
d = 11 units if rounded to nearest whole number
