Answer:
Plus or minus 12
Step-by-step explanation:
You can indeed use the quadratic formula (a = 3, b = 0, c = -432), but that'd be overkill. Instead, simplify the given 3y^2 = 432 by dividing both sides by 3: y^2 = 144. Next, take the sqrt of both sides, remembering to preface your answers by "plus or minus:" y = plus or minus sqrt(144) = plus or minus 12.
Answer:
rectangles are similar figures, thus if scaled copies of each other then the ratios of corresponding sides must be equal
compare ratios of lengths and widths
rectangles A and B
k = = ← ratio of lengths
k = = ← ratio of widths
scale factors are equivalent, hence rectangle A is a scaled copy of B
rectangles C and B
k = = ← ratio of lengths
k = = ← ratio of width
scale factors (k ) are not equal, hence C is not a scaled copy of B
rectangles A and C
k = = ← ratio of lengths
k = ← ratio of widths
the scale factors are not equal hence A is not a scaled copy of C
