First attempt to break the top portion up so the negative signs don’t confuse you.
(2 x -2) x (-2 x -4)/ 2 x 2
= (-4) x (8)/ 4
= -32/4
= -8
*Remember that multiplying two negative numbers give you a positive number
If two triangles are similar then the
corresponding sides are in proportion. Thus,
AB / AU = BC / UV = AC / AV
AB / (20x+108) = 703 / 444
Where AB is equivalent to:
AB = AU + UB
AB = 20x + 108 + 273
AB = 20x + 381
Therefore going back to the first equation:
(20x + 381) / (20x + 108)
= 703/444
444 (20x + 381) = 703 (20x + 108)
8880x + 169164 = 14060x + 75924
14060x - 8880x = 169164 – 75924
5180 x = 93240
x = 93240 / 5180

An exponent represents a number multiplied by itself that many times. Therefore, 10 to the power of 2 would be 10 multiplied by itself 2 times, coming out to be 100.
