I honestly don't know what to do for b. Maybe it tells us that the minimum area possible is 38.25 in²? or maybe it tells us that the area of just the original photo is 29.75 in²? I don't know.
Answer:
(x-9)(x+2) = x^2 + 2x -9x -18 = x^2 -7x -18
Answer is B
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 81 = 15²
x² + 81 = 225 ( subtract 81 from both sides )
x² = 144 ( take the square root of both sides )
x =
= 12
