A carpenter is designing rectangular picture frames to sell at a local craft fair. The frames will be made of wood with a uniform width
around the picture, and each frame will have an opening for a 5-inch by 7-inch picture,
Write an equation that represents the area of the wooden frame, y, in terms of the width of the frame, x.

y= 4x^2+24x

a the answer hopes this

step-by-step explanation:

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.
