  ∠KPN = ∠MPL = 180° -60° -70°

  ∠KPN = 50°

Which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula?
lbvjy [14]

Answer:

x = StartFraction negative

(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction

Step-by-step explanation:

0 = – 3x2 – 2x + 6

It can still be written as

– 3x2 – 2x + 6 =0

Quadratic formula=

-b+or-√b^2-4ac/2a

Where

a=-3

b=-2

c=6

x= -(-2)+ or-√(-2)^2-4(-3)(6)/2(-3)

x = StartFraction negative

(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction

zlopas [31]

Answer:

\frac{5x+1}{5}

Step-by-step explanation:

<em><u>Given Condition:</u></em>

=> x+50%-30%

=> x+20%

=> x+ \frac{20}{100}

<u>LCM = 100</u>

=> \frac{100x+20}{100}

Taking 20 common

=> \frac{20(5x+1)}{100}
