Step-by-step explanation: PEMDAS use this ok first you do 7x7 to equal 49 then add 50 to equal 99. then do 5x5x5 to equal 125. the parentheses are gone and the 5x5x5 is gone now the problem is 125-2x3-99. to finish you multiply 2x3 to equal 6 now 125-6-99=20 answer-20

How many solutions does the following equation have? -1/3x2=5/6+1/3y2 5y2=25/2-5x2

Phantasy [73]

The system of equations have 2 solutions

<h3>How to determine the number of solutions?</h3>

The system of equations is given as:

-1/3x² = 5/6 + 1/3y²

5y² = 25/2 - 5x²

Next, we plot the graph of the system of equations.

From the attached graph, the equations intersect at two points

Hence, the system of equations have 2 solutions

Comppete the equation X^2+y^2-10x+6y=15

mart [117]

I believe you meant: Use completing the square to determine the center and radius of the circle represented by this equation: X^2+y^2-10x+6y=15

x^2 - 10x + 25 - 25 + y^2 + 6y + 9 - 9 = 15
Then:
(x-5)^2 + (y+3)^2 = 24 = 2sqrt(6)

This circle is centered at (5,-3) and has radius 2sqrt(6).

(2x+4)^2 - (x-5)^2 = 26x Please solve (explained)

Zina [86]

Expand the squared binomials:

$(2x+4)^2=4x^2+16x+16$

$(x-5)^2=x^2-10x+25$

Then

$(4x^2+16x+16)-(x^2-10x+25)=3x^2+26x-9=26x$

$\implies3x^2-9=0$

$\implies3x^2=9$

$\implies x^2=3$

$\implies x=\pm\sqrt3$

216q^3+15q^3 please help me solve it

katrin [286]

Answer:

231q^3

Step-by-step explanation:

Just add them together. They have the same expressions. Whenever you see a number with an ending similarly to another such as 3x and 2x, they can add together.

This is no different. If something is 6x^2 and another is 7x^2, you would add them to get 13x^2.
