The number that needs tο be added tο cοmplete the square is 90.25.

In algebra, a quadratic equatiοn is any equatiοn that can be rearranged in standard fοrm as where x represents an unknοwn value, and a, b, and c represent knοwn numbers

Tο cοmplete the square fοr the quadratic equatiοn x² - 19x + 23 = 0, we need tο add a number that is equal tο half οf the cοefficient οf x (which is -19) squared.

Sο,

(-19/2)² = 90.25

Therefοre, we need tο add 90.25 tο bοth sides οf the equatiοn:

[tex]x^2 - 19x + 23 + 90.25 = 90.25[/tex]

Then we can rewrite the left side as a perfect square:

[tex](x - 9.5)^2 = 90.25[/tex]

Now we can take the square root of both sides to solve for x:

x - 9.5 = ±√(90.25)

x = 9.5 ± 9.5√(2)

Hence, the number that needs to be added to complete the square is 90.25.

The number of bags of sand needed to fill the sandbox is 18 bags

Volume = L × W × H

= 4 1/2 × 4 × 1/2

= 4.5 × 4 × 0.5

= 9 ft³

Number of bags of sand needed to fill the sandbox = volume of the sandbox ÷ quantity of each bag

= 9 ft³ ÷ 1/2 fr³

= 9 × 2/1

= 18 bags

Answer:

33

Step-by-step explanation:

The bottom angle is a completely straight line, and that means the angle is 180 degrees.

180 - 81 = 99

So, this means 3x = 99. We need to isolate the variable, so we have to divide everything by 3.

x = 33

Answer:

waaait i know how to do this lol ( i feel like this is correct)

x = 33

Step-by-step explanation:

so a line is 180 right?

so make the equation like this

180 = 81 + 3x

now solve for x by doing algebra

(minus both sides by 81)

3x = 99

x = 33

Answer:

$47.75

Step-by-step explanation:

Where are given that the cost of medical service delivery is given by the expression

c=0.5m+10

m= the number of miles

when the number of miles is 75.5 mile we want to find the cost

put m=75.5 in the expression

c=0.5(75.5)+10

solving for c we have

c=37.75+10

c=47.75

Therefore the cost will be $47.75 for a distance of 75.5miles
