Answer: 10a + 15b
Step-by-step explanation:
To answer this question and you will use exponents.
When you fold your paper three times, it is represented as two cubed or 2^3.
When you for your other sheet of paper two times, it is represented as two squared or 2^2.
Put Both of these together and you have 8+4 which equals 12.
It will take 12 layers of paper.
(x+1)(x-2) = x(x-2) + 1(x-2)
= x.x - x . 2 + 1. x - 1 . 2
= x² - 2x + x -2
= x²-x -2

Answer:
120m²
Step-by-step explanation:
length x width = 12 x 10
= 120
I got 180 because (although the picture is smaller and digital meaning I may be off) angle AOD = 85 degrees while angle BOC = 95. 95 + 85 = 180.
