1)the last one 2) g(x) is function beacause fx is one - to-one
7.50*4=30
40*4=160
160-30=130
130\4=32.5
so each boy has left 32.5 with him
Remember that A squared plus B squared equals C squared.
Since sides F_D and D_E are both 3, the answer cannot be 4.2 or 2.4.
SO basically you just add 3 + 3 = (The side F_E, which you can get by putting numbers in the formula), you should get your answer.
3² + 3² = Line EF²
9 + 9 = Line EF²
18 = Line EF²
√18
You get the idea. Hope this helps!
30 is 20% of 150.
30/x = 20/100
30 * 100 = 20 * x
(30 * 100)/20 = x
x = 150
