Diana wants to decorate her floor with a shaggy pink rug. the area of the square feet. which of the following could be the dimensions of the room, in feet?

(2y+z) (y+3)

Step-by-step explanation:

Area of the room is 2y^2 + 6y + yz+ 3z

We apply grouping method

we group first two terms and last two terms

We take out GCf from each group

GCF of 2y^2 + 6y is 2y

GCF of yz + 3z is z

Factor out y+3

(2y+z) (y+3)

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.

do your own work and don"t cheat.
