Alright so first you wanna use the inverse operation for the number that doesnt have the variable.

Math:

14-6=8

now that you have 4x=8 simply divided 8 by 4 and you would get 2 =x

To check the answer just simply switch x with 2 and done.

good luck!

to solve you would subtract 6 to both sides of the equation, the equation is now 4x=6-14. 6-14 is 8 so the equation would be 4x=8. then you would divide 4 to both sides and the ANSWER IS x=2

An ellipse is centered at the origin. Find it’s equation.

Answer:

(x)^2 (y)^2

---------- + --------- = 1

4 3

Step-by-step explanation:

The standard equation for an ellipse is

(x-h)^2 (y-k)^2

---------- + --------- = 1

a^2 b^2

The center is at (h,k)

The vertices are at (h±a, k)

The foci are at (h±c,k )

Where c is sqrt(a^2 - b^2)

It is centered at the origin so h,k are zero

(x)^2 (y)^2

---------- + --------- = 1

a^2 b^2

The center is at (0,0)

The vertices are at (0±a, 0)

The foci are at (0±c,0 )

The vertices are (±2,0) so a =2

The foci is 1

c = sqrt(a^2 - b^2)

1 = sqrt(2^2 - b^2)

Square each side

1 = 4-b^2

Subtract 4 from each side

1-4 = -b^2

-3 = -b^2

3= b^2

Take the square root

b=sqrt(3)

(x)^2 (y)^2

---------- + --------- = 1

I will give brainliest 100=2(5x+3+2) show work please

Debora [2.8K]

Answer is 9.5- explanation- if u substitute 9.5 in the equation 2(5 x 9.5+ 5 = so multiply 9.5 times 5 which equals 47.5 then multiply by the 2 which equals 95 plus the 2+3=5 - 95+5 equals 100 (sorry I’m bad at explaining)

Compare and Contrast a square and an equilateral triangle? Be sure to communicate and discuss using mathematical language, ideas

ella [17]

The comparison and contrast between a square and an equilateral triangle are stated and explained below:

What is a square? A square is a plane shape with an equal length of sides. This implies that the measure of its length is the same as that of its breadth.

What is an equilateral triangle? A triangle is a plane shape with three sides, and a sum of its internal angles to equal $180^{o}$ . Thus an equilateral triangle is a type of triangle with equal lengths of sides, and therefore equal internal angles.
