They found 15 seashells ( can you make this a brainliest ansswer pls )
Answer:
Yes, they are similar. The answer you would click is Yes, the corresponding sides are proportional.
Step-by-step explanation:
The second figure is a dilation of the first, making them similar. The dilation is by a factor of 2 and a half.
Well you are given the roots.
if we have 3 it would.have to be x^3. So something like:
y = ax^3 + bx^2 + cx + d
this could.also be written:
y = (x + a) (x + b) (x + c)
when you are able to write it like this, we know that the opposite of a, b, and c are roots. this is because if we can make any of the insides of the 3 parenthesis equal 0 then y = 0 and that x.is a root. Well if we know the 3 roots that x will be then we just have to figure out the a, b, and c. So let's plug our roots in.
y = (-1 + a) (-5 + b) (-3 + c)
now we have to make each parenthesis equal 0 to find what a, b, and c should be. It is obvious a = 1 to make.that one zero and b = 5 and c = 3. So we know a, b, and c. now let's plug.those into our first equation.
y = (x + 1) (x + 5) (x + 3)
this is your equation. You can multiply out if necessary
Answer:

Step-by-step explanation:
B) because a you pay less and get less b you get more and pay more
