Step-by-step explanation:

Use the distance formula to find the distance between coordinates.

d = √((2--4)^2 + (5-0)^2) \nd = √((2+4)^2 + (5)^2) \nd = √((6)^2 + (5)^2) \nd = √(36 + 25) \nd = √(61) \nd=7.81

Answer:

x=+12

Step-by-step explanation:

4(x+6)=6x=16


We move all terms to the left:


4(x+6)-(6x)=0


We add all the numbers together, and all the variables


-6x+4(x+6)=0


We multiply parentheses


-6x+4x+24=0


We add all the numbers together, and all the variables


-2x+24=0


We move all terms containing x to the left, all other terms to the right


-2x=-24


x=-24/-2

Jamina drove for 2 hours at an average speed of 40km/h. She then drove for 3 hours at an average speed of 50km/h. What was her average speed for the whole journey?

Answers

Remark

Average Speed = Total distance divided by total time.

Total Time

2 hours + 3 hours = 5 hours.  The total time is 5 hours.

Total Distance

d = rate  * time

d1 = 40 km/hour * 2 hours = 80 km

d2 = 50 km/hour * 3 hours = 150 km

d = d1 + d2

d = 80 + 150 = 230 km

Average Speed

Av = Total distance / Total Time = 230 / 5 = 46 km/hr

what is the length of the hypotenuse of a right triangle with legs that measure 8 and 13 cm round the answer to the nearest hundredth

Answers

use pythagoreaan theorem
a^2+b^2=c^2
a and b are teh legnth s of the legs
c is the legnt o fthe hyptonuse

8^2+13^2=c^2
64+169=c^2
233=c^2
square root both sdies
aprox 15.264=c

the legnth is aprox 15.26 cm
8²+13²=c²
64+169=c²
233=c²
15.26=c
