Solve each equation by completing the square <br> 6) m² + 16m – 8 = 0
Natali5045456 [20]

Answer:

m = - 8 ± 6\sqrt{2}

Step-by-step explanation:

Given

m² + 16m - 8 = 0 ( add 8 to both sides )

m² + 16m = 8

To complete the square

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

m² + 2(8)m + 64 = 8 + 64

(m + 8)² = 72 ( take the square root of both sides )

m + 8 = ± \sqrt{72} = ± \sqrt{36(2)} = ± 6\sqrt{2}

Subtract 8 from both sides

m = - 8 ± 6\sqrt{2}

The sum of the measures of angle M and angle R is 90°.
denis23 [38]

Answer:

x = 5

Step-by-step explanation:

We have: The sum of the measures of angle M and angle R is 90°

M + R = 90°    

M = (5x + 10)°

Plug M into (1)

the equation: (5x + 10)° + R = 90°   (2)

R=55° into (2)

(5x + 10)° + 55° = 90°

5x + 10 + 55 = 90

 5x + 65 = 90

5x = 25

x = 5
