I’m pretty sure the answer is 75.4 ft cubed.
Answer:
48
Step-by-step explanation:
200000J/200KJ
Step-by-step explanation:
using k.e=1/2(mv2)
k.e=1×1000×20²/2
k.e=400000/2
k.e=200000J/200KJ
2 root (x-5)=2
Divide each side by 2 (in order to isolate the square root):
Root (x-5) =1
Square both sides to remove the radical sign:
(x-5)=1
Solve:
x=6
To be sure that it is not an extraneous solution, check the solution by replacing the value for the variable in the equation.
2 root (6-5) = 2
The square root of 1 is 1.
2(1)=2
This is correct.
Answer:
(2x + 5)(3x - 7), (x + 4)(x - 2)
Step-by-step explanation:
a = 6, b = 1, c = -35
? × ? = ac = 6 × -35 = - (<u>2</u> × 3 × <u>7</u> × 5)
? + ? = b = 1
3 × 5 -(<em>negative sign from above</em>) 2 × 7 = <u>15</u> <u>- 14</u> = 1 = b
=
=
a = 1, b = 2, c = -8
? × ? = ac = 1 × -8 = -(2 × 2 × 2) = 4 × <u>-2</u>
? + ? = b = 2
4 + <u>(-2)</u> = 2 = b
=
