Triangle ABC is similar to triangle FGH. What is the value of x?

22.5 cm

Step-by-step explanation:

You can make a proportion of the sides of the two triangles: AB/FG = 9/13.5 = 1/1.5 = 2/3

You also can do the same thing with another set of two sides: AC/FH = 12/18 = 2/3.

Then, you know the proportion is 2/3 so you have BC/GH = 2/3 = 15/x

Solving:

multiply both sides by 3x

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
