pogonyaev

Answer:

66 pictures

Step-by-step explanation:

180 ÷ 3 = 60 60 x 2 = 120

120 = 2/3. He took 120 pictures on the first day of his vacation.

120 ÷ 4 = 30 30 x 1 = 30

30 = 1/4. He took 30 pictures of landscapes

120 ÷ 10 = 12 12 x 3 = 36

0.3 = 36. He took 36 pictures of people.

36 + 30 = 66 pictures.

He took 66 pictures of landscapes and people.

Find the area of every square that can be drawn by connecting dots on a 3 dot-by-3 dot grid.

Dafna1 [17]

I could be wrong, but it seems that there are only 2 possible squares in this grid.
•One square has a side length of 2, meaning that the area is 2x2 which is 4 units squared (can be written as 4 units^2)
•The other square has side lengths of 1. 1x1=1 unit^2.

Simplify (3a^4-2a^2+5-10)-(2a^4+4a^2+5a-2)

katrin [286]

Answer:

Step-by-step explanation:

3a^4 -2a^2 + 5 - 10 -(2a^4 +4a^2 + 5a -2)

as given.. i'm wondering if the 5 in the first group is really 5a.. hmmm

I'm guessing that it is... soooo distribute the minus sign

= 3a^4 - 2a^2 +5a -10 -2a^4 -4a^2 -5a +2

= a^4 -6a^2 -8 :) voila that's your answer
