For exercises three and four, the side length and height in the figure at the right are multiplied by 5. Justify your answers. 3. Describe change in perimeter
4. Describe change in area

5. A photo album contains small and large photographs. Each large photograph has side lengths that are twice the side lengths of each small photograph. The area of each small photograph is 24 square inches. What is the area of each large photograph. Explain. ​

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

answer: what is the question you're trying to ask?

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
