Solve 2x2 + 20x = −38.
Makovka662 [10]

Answer:

Correct Answer is C(−5 ±square root 6)

Step-by-step explanation:

2x^2+20x+38=0

2(x^2+10x+19)=0

x^2+10x+19=0

This is a quadratic equation here we have used following formula to find the roots of this equation

x=-b−±square root (b^2-4*a*c))/2*a......(1)

Here,

a=1

b=10

c=19

put values of a, b and c in equation (1)

x=(-10 ±square root(10^2-4*1*19))/2*1

x=(-10 ±square root(100-76))/2

x=(-10 ±square root(24))/2

x=(-10 ±square root(2*2*6))/2

x=(-10 ±2square root(6))/2

x=2(-5 ±square root(6))/2

x=-5 ±square root(6)


Hope this answer will help you

On a map, the distance between Greenville and Fairview is 7 1/4 inches. If the map uses a scale of 1/2 inch = 40 miles, what is
lubasha [3.4K]

The actual distance between cities is 580 miles.

Step-by-step explanation:

Map distance = 7\frac{1}{4} inches = \frac{29}{4}\ inches

Scale used;

\frac{1}{2}\ inches = 40\ miles

Multiplying both sides by 2

2*\frac{1}{2}=40*2\\1\ inch = 80\ miles\\

Now,

\frac{29}{4}\ inches = \frac{29}{4}*80\\\\\frac{29}{4}=29*20\\\\\frac{29}{4}\ inches = 580\ miles

The actual distance between cities is 580 miles.
