Answer:
20
Step-by-step explanation:
Let's start by rewriting the second equation in terms of "x":

Subtract y from both sides:

Now, substitute "5-y" for "x" in the first equation:

Note that:


Cancel out like terms:

Subtract 25 from both sides:

Divide both sides by -10

Now, substitute this value back into either of the equations to solve for x.

Add 15/2 to both sides:

Now, find the difference:

What you need to do is find a common multiple which is 11, Then you divide 22c and 33d by 11 so you get 2c and 3d Then since there is an addition sign you put 2c and 3d is ()
The Final answer is
11(2c+3d)
The perimeter of the smaller triangle is 8+12+16=36. The big triangle has perimeter 54. So our scale factor is 54/36=3/2. So we scale up the short side, 8, by 3/2, giving our answer:
Answer: 12
Answer:
Step-by-step explanation:
1. A square has four sides and all the sides have equal length.
2. Keeping this on mind, you must multply the lenght given in the problem by 4, as you can see below:

3. Therefore, the polynomial expresion that represents the perimeter of the square is
