How many solutions exist for the given equation 1/2 (x+12)=4x-1

Mathematics
2 answers:
Daniel [21]3 years ago

Answer:

x=2

Step-by-step explanation:

1/2 (x+12)=4x-1

Multiply each side by 2

2*1/2 (x+12)=2*(4x-1)

x+12 = 8x -2

x+12 = 8x - 2

Subtract x from each side

12 = 7x -2

Add 2 to each side

14 =7x

Divide by 7

14/7 = 7x/7

2 =x

Steps to solve:

1/2(x + 12) = 4x - 1

~Distribute

1/2x + 6 = 4x - 1

~Subtract 6 to both sides

1/2x = 4x - 7

~Subtract 4x to both sides

-7/2x = -7

~Multiply -2/7 to both sides

x = 2

Best of Luck!

The area of<br>of a rectangle is (14x^4 + 7x^2) cm²<br>and its breadth is 7x^2 cm. Find its length.​
NeTakaya

Answer:

2x^1+1

Step-by-step explanation:

Area=L X W

which means that (14x^4+7x^2) needs to be divided by 7x^2

factorise(14x^4+7x^2) which gives 7x(2x^2+1)

divide 7x(2x^2+1) by 7x^2

gives 2x^2 +1

What additional information would allow you to prove the quadrilateral is a parallelogram?
slavikrds [6]

The additional information that would allow us to prove that the image is a parallelogram is that; Line EJ ≅ Line GJ

<h3>How to prove a Parallelogram?</h3>

The six basic properties of parallelograms are primarily;

  • Both pairs of opposite sides are parallel
  • Both pairs of opposite sides are congruent
  • Both pairs of opposite angles are congruent
  • Diagonals bisect each other
  • One angle is supplementary to both consecutive angles (same-side interior)
  • One pair of opposite sides are congruent AND parallel.

Now, looking at the parallelogram properties above and comparing with the given image of the quadrilateral attached, we can say that the additional information that would allow us to prove that the image is a parallelogram is that; Line EJ ≅ Line GJ
