Answer:
x = 0 or x = -2
Step-by-step explanation:
x^4+8x=0
Step 1: Factor left side of equation.
x(x+2)(x2−2x+4)=0
Step 2: Set factors equal to 0.
x=0 or x+2=0 or x2−2x+4=0
x=0 or x=−2
Answer:
the solution is (-1/2, 6).
Step-by-step explanation:
Next time, please share the instructions.
Start by carrying out the indicated multiplication:
2x + 2y = 23 - 2y
Consolidate l ike terms: combine 2y and -2y: result: +4y on the left side:
2x + 4y = 23
Let's solve this system using elimination by substitution. Multiply 2x + 4y = 23 by -3 to obtain a -6x term:
-3(2x + 4y = 23) = -6x - 12y = -69. Now combine this result with the second equation:
-6x - 12y = -69
6x + 5y = 20 + 7
-------------------------
- 7y = -42
Dividing both sides by -7, we get y = 6. Subbing 6 for y in the 2nd equation, we get:
6x = 27 -5(6), or
6x = 27 - 30 = -3
Then x = -3/6, or x = -1/2
and the solution is (-1/2, 6).
Answer: 64 cm ²
Step-by-step explanation:
The perimeter of this rectangle will be:
= 2 * Length + 2 * Width
= 2 * 10 + 2 * 6
= 20 + 12
= 32 cm
The square has the same perimeter. Squares have 4 equal sides so each side of the square must be:
= 32 / 4
= 8 cm
Area = Length * Width
= 8 * 8
= 64 cm ²
Answer:
To provide a situation of 1 and O, here is a situation.
Step-by-step explanation:
The acceleration would be 1.
If the acceleration is 10 m/s, the object will gain more speed.
On the other hand, if the acceleration is -10m/s, then the object will lose speed.
In the case of 1, the object gained more speed, in the case of 0, the object will lose speed.
