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

2(x+y)=23-2y <br>6x-7=20-5y​
slavikrds [6]

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).

Two sides of a rectangle are 10 and 6cm each. Calculate the area of a square with the same perimeter as that of the rectangle
KengaRu [80]

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

dangina [55]

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.
