Answer:

(x + 6)² = 13

Step-by-step explanation:

Given

x² + 12x + 23 = 0 ( subtract 23 from both sides )

x² + 12x = - 23

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(6)x + 36 = - 23 + 36

(x + 6)² = 13

Lynn plotted point G, 3 units to the left and 2 units above point F . Where did Lynn plot point G ?
bekas [8.4K]

Answer:

(2, 6)

Step-by-step explanation:

Point G has a coordinate of x = 5, and y = 4, that is (5, 4).

If Lynn plots point G, such that:

G is 3 units to the left of point F, the x-coordinate of point G = 5 - 3 = 2

G is 2 units above point F, the y-coordinate of point G = 4 + 2 = 6.

Therefore, Lynn plotted point G at x = 2, and y = 6. Which is (2, 6)

Prove that angle ADC is congruent to angle CBA <br><br> with solution!
vova2212 [387]

Step-by-step explanation:

< i'll use this too represent angle

this is only presuming that this is a parallelogram and i also don't know what those numbers mean

< ACB = < CAD         (alt <s of DA II CB)             A

< ACD = < CAB        (alt <s of DC II AB)              A

AB is common                                                     S

therefore, ∆ADC is congruent to ∆CBA

if ∆ADC is congruent to ∆CBA

then < ADC = < CBA

Solve the equation. Then check your solution.<br> -<br> (3a + 4) = 7<br> Helppp
Sati [7]

Answer:

a= -3\frac{2}{3} or ≈ -3.66

Step-by-step explanation:

-(3a+4)=7

-3a-4=7

<em>Add 4 to both sides</em>

-3a=11

<em>Multiply both sides by -1</em>

3a= -11

Divide both sides by 3

a= -3\frac{2}{3}

How does the order of steps in solving an equation relate to order of operations
Akimi4 [234]
If you dont follow the right steps in the right order or properly, you won't end up with the right answer:
For example 3 x 5 + 7
If you do multiplication then add you get 22 which is correct.... but!!
If you add then do multiplication you get 36 which isn't right

Remember always follow PEMDAS
P-Parenthesis
E-Exponents
M or D- Multiplication or division (go left to right)
A or S- Addition or Subtraction (go left to right)
