1. Ais when you move a shape left, right, up, or down.2. Ais when you turn a figure clockwise or counter- clockwise for 90 or 180 degrees.3. A___is when you flip the shape across the y or x axis.4. A___is when you stretch or shrink a shape. All sides are stretched or shrunk the same amount, so you will end up with a similar figure. This means corresponding sides are inand corresponding angles remain___. This is the only type of dilation that changes the size of a figure. Word box: proportion, translation, rotation, congruent, reflection, dilation

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.

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
