Answer:

5x²+4x+3

Step-by-step explanation:

I think, first you start with simplifying no. in the bracket in both sides then remove the bracket work with the remained according to their operation

Answer:

5x^2 + 4x + 3.

Step-by-step explanation:

While I'm a little confused on what is closed and open parenthesis/brackets, I think I understand what you mean. In (5x^2+3x-2)+(3x-2x+5), the brackets can simply be removed as there is no multiplication between them. This means we get 5x^2 + 3x - 2 + 3x - 2x + 5. Combining like variables, we get 5x^2 + 4x + 3.

$\huge \huge \huge\huge\mathrm{ \boxed{ \boxed{ \boxed{ \boxed{ \boxed {\boxed{ \huge\mathfrak{ Solution}}}}}}}}$

$\sqrt{x - 1} - x = - 7$

$\sqrt{x - 1} =x - 7$

$x - 1 = (x - 7) {}^{2}$

$x - 1 = {x}^{2} + 49 - 14x$

${x}^{2} - 14x + 49 - x + 1 = 0$

${x}^{2} - 15x + 50 = 0$

${x}^{2} - 10x - 5x + 50 = 0$

$x(x - 10) - 5(x - 10) = 0$

$(x - 5)(x - 10) = 0$

$x = 5 \: \: \: or \: \: \: x = 10$

Select the correct answer. Which point lies on the circle represented by the equation (x + 7)2 + (y − 10)2 = 132? A. (5,12) B. (

Feliz [49]

Answer:

B. (-7,-3)

Step-by-step explanation:

Given the circle: $(x + 7)^2 + (y - 10)^2 = 13^2$

The point (x,y) which lie on the circle are the coordinate which satisfies the given equation of the circle.

We now consider the given options.

<u>Option A (5,12)</u>

When x=5, y=12

$(5 + 7)^2 + (12 - 10)^2 =12^2+2^2=148\neq 169= 13^2$

<u>Option B (-7,-3)</u>

When x=-7, y=-3

$(-7 + 7)^2 + (-3 - 10)^2 =0^2+(-13)^2= 169=13^2$

<u>Option C (-6,-10)</u>

When x=-6, y=-10

$(-6 + 7)^2 + (-10 - 10)^2 =1^2+(-20)^2=401\neq 169= 13^2$

<u>Option D (6,23)</u>

When x=6, y=23

$(6 + 7)^2 + (23 - 10)^2 =13^2+13^2=338\neq 169= 13^2$

We can see that only (-7,-3) satisfies the equation of the circle. Thus it is the point which lies on the circle.

The correct option is B.
