Answer:

y² -7y+12

Step-by-step explanation:

first, you have to multiply each character on the first parenthesis to the second one, one by one. just like the picture attached.

then, combine all of the same variable. like the 2 variable that has y.

Which statement is NOT true about the ratio of the leg lengths of increment ΔLRM and increment ΔJSK?

Alona [7]

Given the similar triangles, it can always be noted that similarity can be derived from the proportionality of the leg lengths, however it is not true the the ratio of the proportion of the leg lengths is equal to the slope of the triangles. Thus the false statement is:
A] The slope of the hypotenuse is represented by the ratio of the leg lengths.

What is the length of the side of a right triangle that has a side length of 12in and a hypotenuse that measures 15ft

Viktor [21]

Answer: 14.96ft

Step-by-step explanation:

1. To solve this exercise you must apply the Pythagorean Theorem, which is:

$a=\sqrt{b^{2}+c^{2}}$

Where $a$ is the hypotenuse, and $b$ and $c$ are the other sides of the triangle.

2. You have that the sides given measures 12 inches. 1 feet has 12 inches. Therefore, this side measures 1 feet.

2. Then, when you solve for one of the sides and substitute the values given in the problem into the formula shown above, you obtain that the length of the side of the rigth triangle is:

$b=\sqrt{(15ft)^{2}-(1ft)^{2}}$

$b=4\sqrt{14}=14.96ft$

Answer:

1. Ben

Let the number of days be x.

Let the total no. of shares be y

$No.\ of\ shares\ on\ Day\ 0=2\\No.\ of\ shares\ on\ Day\ 1\ = 2*3\\No.\ of\ Shares\ on\ Day\ 2\ =\ 2*3*3\\No.\ of\ Shares\ on\ Day\ 3\ = 2*3*3*3\\No.\ of\ Shares\ on\ Day\ x\ =2*3^x\\As\ Total\ no.\ of\ shares\ = y\\y=2*3^x$

2. Carter

Let the no. of days be x

Let the total no. of shares be y

$No.\ of\ shares\ on\ Day\ 0=10\\No.\ of\ shares\ on\ Day\ 1\ = 10*2\\No.\ of\ Shares\ on\ Day\ 2\ =\ 10*2*2\\No.\ of\ Shares\ on\ Day\ 3\ = 10*2*2*2\\No.\ of\ Shares\ on\ Day\ x\ =10*2^x\\f(y)=10*2^x$
