Answer:

Step-by-step explanation:

Using BF as the reflective points, A will become C and G will become E. It also works the other way around: C becomes A and E becomes G.

You would be helped if you could actually try it. If you put a mirror on BF and look first at A and G and then move so you can see C and E you should be convinced of the reflective property. Then turn the mirror around and look again.

These things look to be quite simple but it took many centuries before they were properly explained, and even then there were difficulties.

The second choice does not work at all. You cannot see any reflection the way you can with the first choice.

Answer 1a 18 1b 36 1c 648

1a : if you look at the shape you will see its made of squares. I counted the squares, its 18.

1b : one side is 6 in. since its a square all sides are equal. so multiply 6 by 6 to get 36.

1c : this one is easy. We take the number of squares across the surface (18) by the area of each square (36) it is 648.

Also sorry I didn't make this clearer earlier.

To visit his grandmother, Luis takes a train 6.376.376, point, 37 kilometers and a car 5.455.455, point, 45 kilometers.

murzikaleks [220]

Answer:

Luis traveled 11.82 km in total.

Step-by-step explanation:

<em>The statement should say</em>: To visit his grandmother, Luis takes a train 6.37 kilometers and a car 5.45 kilometers. How many kilometers is Luis's journey in total?

Hence, to find the total distance traveled by Luis we must add the distances of the train (6.37 km) and the car (5.45 km):

$d = d_{t} + d_{c} = 6.37 km + 5.45 km = 11.82 km$

Therefore, Luis traveled 11.82 km in total.

I hope it helps you!

Find the possible value or values of y in the quadratic equation 4 – 4y – y 2 = 0. A. y = –3, y = –1 B. y = 2 C. y = –2 + 2√ 2,

xz_007 [3.2K]

4 - 4y - y² = 0
-y² - 4y + 4 = 0
y = -(-4) ± √((-4)² - 4(4)(-1))
2(-1)
y = 4 ± √(16 + 16)
-2
y = 4 ± √(32)
-2
y = 4 ± 4√(2)
-2
y = 4 + 4√(2) or y = 4 - 4√(2)
-2 -2
y = -2 - 2√(2) or y = -2 + 2√(2)

The answer is C.
