Answer:
x=4/14
Step-by-step explanation:
step one:
3x^2+8x-4=0 turns into -
6x+8x-4=0
Step two:
6x+8x-4=0 turns into -
14x-4=0 because you have to combine like terms
Step three:
14x-4= 0 turns into
14x=4 to get x by itself
Step four:
14x=4 turns into -
x=4/14

Step-by-step explanation:
Use the distance formula to find the distance.
D=√(x2-x1)^2 + (y2-y1)^2 (the entire equation is square rooted)
Plug in your numbers
D=√(4-1)^2 + (8-2)^2
D=√(3)^2 + (6)^2
D=√9+36
D=√45
D=3√5
D=6.7
Answer:
65 square units
Step-by-step explanation:
The base of the pyramid is 5 by 5 , surface area is 25 square units.
the side of each one is 4 units "high" and 5 long at the base and to find the are of a triangle you multiple base times height then dived by 2. Therefore each side of the triangle is 10 units square. You have 4 sides so...
40 (total of all the sides ) +25 ( base ) = 65
Answer:
37
Step-by-step explanation:
