Answer:

4 units

Step-by-step explanation:

Since the two triangles are similar, their sides are proportional. To find the length of the side, you need to use the distance formula:

\sqrt{(x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2} }

The coordinates you will use are (0, 0) and (-4, 0) because they correspond to points X and Y in Triangle PQR:

\sqrt{(0 - (-4))^{2} + (0 - 0)^{2}}

Then, simplify everything under the radical:

\sqrt{16}

Finally, take the square root of 16:

\sqrt{16} = 4

For a system of equations such as this, add both of the equations together. The d values will cancel each other out, making 2e=-4. This means that e=-2. If you plug this into one of the equations, you will have d + (-2) = 1. Isolate the variable by adding -2 to both sides: d=3. Written in the format described above (d,e), your answer is (3, -2).

Ok help me please guys ..what is 61=3b+7 ?
Neporo4naja [7]
61 = 3b + 7

3b + 7 = 61

3b = 61 - 7

3b = 54

b = 54/3

b = 18.
