Answer:

40n

Step-by-step explanation:

(40+n): The first one is asking to add forty and n, however the question is asking for multiplication so that is not an answer.

(n-40): This one is using subtraction, so this one is an obvious no.

(40/n): This phrase represents division, this could be a possibility because it is the inverse operation, however the numbers need to be reversed.

(40n): Im thinking that you got confused because there was no operation symbol. Whenever a number and a variable are attached without an operation symbol in between, you multiply. So, this is the correct answer.

Suppose you have an isosceles triangle with a 90° angleIf the congruent sides each measure 9 feet, what is the length of the sid

Zepler [3.9K]

Answer:

$9\sqrt{2}$ feet

Step-by-step explanation:

Consider the attached figure.

An isosceles triangle is a triangle in which two sides are equal.

$AB=BC=9$ feet

According to Pythagoras theorem,

square of hypotenuse is equal to sum of squares of other two sides.

$AC^2=AB^2+BC^2\\AC^2=9^2+9^2\\AC^2=81+81\\AC^2=162\\AC=\sqrt{162}$

$AC=9\sqrt{2}$ feet
