Find the distance between the points (0,-8) and (8,-3). The answer must be a whole number or a fully simplified radical expressi

BigorU [14]

Answer:

The distance in radical expression form is d= $\sqrt{89}$

Step-by-step explanation:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(8-0)^2+(-3-(-8))^2}\\d=\sqrt{(8)^2+(5)^2}\\d=\sqrt{(64)+(25)}\\d=\sqrt{89}\\$

Which is bigger half of 40 or one fourth of 20

Kisachek [45]

Half of 40 = 0.5 x 40 = 20 .

One fourth of 20 is smaller than 20.
You don't even have to calculate it.

2x(x+4)+7+=(x+8)+ 2x(x+1)+12=

Katena32 [7]

Answer:

x=2.600

Step-by-step explanation:

2x(x+4)+7+=(x+8)+ 2x(x+1)+12

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-> 2*x*(x+4)+7+-((x+8)+2*x*(x+1)+12)=0

-> ((2x•(x+4))+7)-(((x+8)+2x•(x+1))+12) = 0

-> (2x • (x + 4) + 7) - (2x2 + 3x + 20) = 0

-> 5x - 13 = 0

-> Add 13 to both sides of the equation :

5x = 13

Divide both sides of the equation by 5:

x = 13/5 = 2.600

Find the area of a triangle whose sides are 5 m, 6 m and 9m,( use root 2 =-1.41 m)

dlinn [17]

The area of the triangle is 14.1 square meters

<h3>How to determine the triangle area?</h3>

The side lengths are given as:

5m, 6m and 9m

Calculate the semi-perimeter (s) using

s = (5 + 6 + 9)/2

Evaluate

s = 10

The area is then calculated as:

$Area = \sqrt{s(s -a)(s-b)(s-c)$

This gives

$Area = \sqrt{10 * (10 -5)(10-6)(10-9)$

Evaluate the products

$Area = \sqrt{200$

Evaluate the exponent

Area = 14.1

Hence, the area of the triangle is 14.1 square meters
