solve for c.

solve for x.

solve for x.

1) The option is correct.

2) The option x=-2 or x=-3 is correct.

3)  The option is correct.

4) The option is correct.

5)  The option x=-2 or x=-3 is correct.

Step-by-step explanation:

1) Given equation is

Now to solve the equation for c:

Squaring on both sides we get

Therefore the option is correct.

2) Given equation is

Now to solve the equation for x:

Squaring on both sides we get

which is a quadratic equation in x.

We can solve it by finding factors

x+2=0 or x+3=0

Therefore  x=-2 or x=-3

Therefore the option x=-2 or x=-3 is correct.

3)  Given equation is

Now to solve the equation for c:

Squaring on both sides we get

Therefore the option is correct.

4) Given equation is

Now to solve the equation for x:

Squaring on both sides we get

Therefore the option is correct.

5) Given equation is

Now to solve the equation for x:

Squaring on both sides we get

which is a quadratic equation in x.

We can solve it by finding factors

x+2=0 or x+3=0

Therefore  x=-2 or x=-3

Therefore the option x=-2 or x=-3 is correct.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

0 is its x and y coordinate
