I If x > 0 and x^2-2x-35 = 0, then the value of x^2 is 3​

x^2 = 49

Step-by-step explanation:

Notice that the polynomial on the left of the equation can be factored out as:

x^2 - 2 x - 35 = (x - 7) (x + 5)

Then the equation:   x^2 - 2 x - 35 = = 0

gives two solutions as follows:

(x - 7) (x + 5) = 0 Then either binomial factor must be zero, and therefore, x = 7 or x = -5

Since we are told that x is POSITIVE, the x = 7, and its square is 7^2 = 49.

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
