Factor a square root of 14 out of every expression to get:

\sqrt{14}*(\sqrt{4}-1+\sqrt{9)

\sqrt{14}*(2-1+3)

4*\sqrt{14}

Thus, the expression is equal to four times the square-root of 14.  The second answer is correct.

Abcd is a rectangle if DB=26 and DC=24 find bc
Anettt [7]
Let's solve this problem step-by-step.

STEP-BY-STEP EXPLANATION:

Let's first establish that triangle BCD is a right-angle triangle.

Therefore, we can use Pythagoras theorem to find BC and solve this problem. Pythagoras theorem is displayed below:

a^2 + b^2 = c^2

Where c = hypotenus of right-angle triangle

Where a and c = other two sides of triangle

Now we can solve the problem by substituting the values from the problem into the Pythagoras theorem as displayed below:

Let a = BC

b = DC = 24

c = DB = 26

a^2 + b^2 = c^2

a^2 + 24^2 = 26^2

a^2 = 26^2 - 24^2

a = square root of ( 26^2 - 24^2 )

a = square root of ( 676 - 576 )

a = square root of ( 100 )

a = 10

Therefore, as a = BC, BC = 10.

If we want to check our answer, we can substitute the value of ( a ) from our answer in conjunction with the values given in the problem into the Pythagoras theorem. If the left-hand side is equivalent to the right-hand side, then the answer must be correct as displayed below:

a = BC = 10

b = DC = 24

c = DB = 26

a^2 + b^2 = c^2

10^2 + 24^2 = 26^2

100 + 576 = 676

676 = 676

FINAL ANSWER:

Therefore, BC is equivalent to 10.

THIS IS SO CONFUSING! I hate this
djyliett [7]

Answer:

2 and 6 for the circles.

-18 for the square.

Step-by-step explanation:

-3 times a number is -6.

-3 \times 2 = -6

The number is 2.

2 times a number is 12.

2 \times 6 = 12

The number is 6.

6 times -3.

6 \times -3 = -18

The number is -18.

How does remote work relate to taking an online class or being an online student (fully online or hybrid)?
Svetach [21]

Answer:

Answered

Step-by-step explanation:

Online courses are those classes which are delivered entirely online. Students study via web cam,  chat rooms and smart boards. Whereas hybrid learning is a combination of both online learning and  traditional in class learning.  Remote work is working away from the work place at your own comfort and choice of location.

What does 12(6-k) equal​
gregori [183]

\text{Hey there!}

\rightarrow\text{What does 12(6 - k) equal?}

\text{Well, the formula is: a(b + c) = a(b) + a(c) = ab + ac}

\bf{12( 6 - k) = 12(6) - 12(k)= \underline{72 -12k}}

\boxed{\boxed{\text{\bf{Thus, your answer is: 72 - 12k}}}}\checkmark

\text{Good luck on your assignment and enjoy your day!}
