Answer:

Step-by-step explanation:

ΔABC is congruent with ΔDEF. That means the corresponding sides are congruent.

Look at the order of the letters. EF are the last two letters of ΔDEF. So this corresponds with the last two letters of ΔABC. Therefore, EF ≅ BC.

EF ≅ BC

x² + 8x = 48

x² + 8x − 48 = 0

(x + 12) (x − 4) = 0

x = -12 or 4

Since x can't be negative, x = 4.

The difference between the masses is
4.55·10¹³ kg -1.78·10¹² kg
= 4.55·10¹³ kg - 0.178·10¹³ kg
= (4.55 -0.178)·10¹³ kg
= 4.372·10¹³ kg

Rounded to the appropriate precision, the mass of the Antarctic iceberg exceeds that of the Rock of Gibraltar by ...
4.37·10¹³ kg

I need help thank you

Andreyy89

Answer: A

Step-by-step explanation:

For this problem, we need to understand how translations work.

As you can see, the triangles only slide to the right side, along the x axis. Therefore, we can eliminate B and C.

Now, we can see that the triangle has shifted by +8 units. Therefore, A is the correct answer.
