Find the missing length the triangles are similar.
ch4aika [34]

Answer:

Step-by-step explanation:

The missing length is 13 because,

Lets say the top triangle is A and the bottom triangle is B.

Triangle A gives us the side GF, and Triangle B gives us the sides TU and ST. Since the triangles are similar(as stated in the problem), we can pair 2 sides GF(A) and TU(B) which is 11:22.(one way I usually figure which sides are similar is by first- matching the hypotenuse, then checking which of the remaining two is longer.. if that made any sense). You can see that their relationship is x2 or /2 (In another word, from A to B is multiplication- ex: 11 * 2 is 22, and from B to A is division- ex 22/2 is 11.) Since the missing number is the hypotenuse of triangle A and you know the Hypotenuse of triangle B all you have to do is divide side TS by 2 to get side SF. So the missing side is 13.

Answer: 13

Nina [5.8K]

Answer:

33.60 is your answer

Step-by-step explanation:

Remember to add based on place value.

Note that 10.70 is the same as 10.7

11.15 + 11.75 = 22.90

22.90 + 10.7 = 33.60

Angelina_Jolie [31]

The simplification form of the expression is 3x²/2 + 2x or three-halves x squared + 2 x option second is correct.

<h3>What is the area of the rectangle?</h3>

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

We have:

A community garden with raised beds is being redesigned. The area of the new rectangular beds can be expressed as one-half x (3 x + 4).

The expression:

\rm = \dfrac{1}{2}(3x+4)

By using the distributive property:

\rm = \dfrac{1}{2}\times3x^2+\dfrac{1}{2}\times4x

\rm = \dfrac{3}{2}x^2+2x

Thus, the simplification form of the expression is 3x²/2 + 2x or three-halves x squared + 2 x option second is correct.
