What is the intermediate step in the form (x + a)2 = b as a result of completing the
Eddi Din [679]

Answer:

(x + 7)^2 = 64

Step-by-step explanation:

x^2 + 23x – 19 = 9x - 4

x^2 + 23x - 9x = -4 + 19

x^2 + 14x = 15 = 0

Completing the square:

(x + 14/2)^2 - (14/2)^2 = 15

(x + 7)^2 - 49 = 15

(x + 7)^2 = 64

Solve for W<br> (W/-5) -4=-2
Simora [160]

Answer: \Large\boxed{W=-10}

Step-by-step explanation:

<u>Given equation</u>

(\dfrac{W}{-5} )-4=-2

<u>Add 4 on both sides</u>

(\dfrac{W}{-5} )-4+4=-2+4

(\dfrac{W}{-5} )=2

<u>Multiply -5 on both sides</u>

(\dfrac{W}{-5} )\times (-5)=2\times(-5)

\Large\boxed{W=-10}

A square has a area of 466.56m squared work out the peremiter
MissTica

Answer:

Perimeter = 86.4 (m)

Step-by-step explanation:

A square (with side x) has an area of 466.56 (m^2)

=> x^2 = 466.56

=> x = sqrt(466.56) = 21.6

=> Perimeter of this square: P = 4(x) = 4(21.6) = 86.4 (m)

Hope this helps!
