(4x + 2y + 6) + (7x + 3y - 4) + (x - 2y + 1) Can someone break this down step by step so i know how to do it please
thankyou .

12x + 3y + 3

Step-by-step explanation:

I totally get you:

1. Remove parenthesis making it: 4x + 2y + 6 + 7x + 3y - 4 + x - 2y + 1

2. Collect Like terms: (4x + 7x + x) + (2y + 3y − 2y) + (6 − 4 + 1)

3. Simplify: 12x + 3y + 3

There you go! I hope this helps! May I please have Brainliest!?!!

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
