The perimeter of triangle XYZ will be:

40r + 30r + 60r = 130r

The area of triangle ABC is n² so the area of triangle XYZ will be n²×r²

Answer:

Part A. Option B.

Part B. Option C.

Step-by-step explanation:

The sides of ΔABC are 30 units, 40 units and 60 units long.

The corresponding sides of ΔXYZ are r times as long as the sides of ΔABC.

Therefore sides of ΔXYZ will be 30r units, 40r units and 60r units.

Perimeter of ΔXYZ = 30r + 40r + 60r = 130r

Option B. is the answer.

If the area of ΔABC is n square units then we have to find the area of ΔXYZ.

Since all sides of ΔXYZ are r times of ΔABC, so area of ΔABC = \frac{1}{2}(Base)(height)

Area of ΔXYZ = \frac{1}{2}(r.height)(r.base)=n(r.r)

= n(r)²

Option C is the answer.

What is the slope of the line with the equation 3x = -y − 5
prisoha [69]

This equation is written in <em>standard form</em>, so we need to change it into <em>slope-intercept form.</em>

<em />

3x = -y - 5

3x + y = -y + y - 5

3x + y = -5

3x - 3x + y = -5 - 3x

y = -5 - 3x

y = -3x - 5

The slope is classified as "m" in this type of equation, so, the slope is -3.

Best of Luck!
