Answer:

yes; 4² + 3² = 5²

Step-by-step explanation:

Pythagorean theorem.

In a right triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides. Hypotenuse is the longest side of the triangle.

4² + 3² = 5²

16 + 9 = 25

25 = 25

Bella cycled a total of 12 kilometers by making 4 trips to work. How many trips will Bella have to make to cycle a total of 18 k

UkoKoshka [18]

6 trips because 1 trip = 3 km
If you divide 18 / 3 it would be 6 and by that multiply the # of trips.

Multiple Representations:Question 1

alexdok [17]

Answer:

y = 27.1

Step-by-step explanation:

We have the value of x:

x = 12

and we need to find the value of y in the expression:

y = x + 15.1

as we can see by the equation, the value of y depends on the value of x.

thus, we substitute x = 12 on the previous equation:

y = 12 + 15.1

y = 27.1

the value of y is 27.1

The midpoint of is point P at (−16,6). If point A is at (−10,8), what are the coordinates of point B? (−42,20) (−22,4) (−13,7) (

statuscvo [17]

Answer:

B (-22 , 4)

Step-by-step explanation:

-16=(-10+x)/2

*2 *2

-10+x=-32

+10 +10

x=-22

6=(8+y)/2

*2 *2

12=8+y

-8 -8

4=y

so B(-22, 4)

Somebody answer !!!!!

Rainbow [258]

Answer:

Step-by-step explanation:

First we have to subtract 5 from both sides

$\sqrt{x-6} +5=12\\\\\sqrt{x-6}+5-5=12-5\\\\\sqrt{x-6}=7$

Now, square both sides

$(\sqrt{x-6})^{2}=7^{2}$

x - 6 = 49

Now, add 6 to both sides

x - 6 +6 = 49 + 6

x = 55
