Part a) Find the expression that gives the perimeter of ∆XYZ
we know that
Perimeter of triangle ABC is equal to
In this problem ∆ABC and ∆XYZ are similar triangles
the scale factor is equal to r
so
therefore
the answer Part a) is
The expression that gives the perimeter of ∆XYZ is 
Part b) Find the expression that gives the area of ∆XYZ
we know that
therefore
the answer Part b) is
The expression that gives the Area of ∆XYZ is 
Answer:
<u>9x² + 42x + 49</u>
Step-by-step explanation:
<u>Identity</u>
In this case, x = 3x and a = 7, so <u>substitute</u> the values.
- (3x + 7)²
- (3x)² + 2(3x)(7) + (7)²
- <u>9x² + 42x + 49</u>
When we say "5 is the third part of 15," we do not imply a sequence: the first part, the second part, the third, and so on. When we speak of the third part, that is a different meaning for the word "third." It means each one of three equal parts that together make up the whole
The basic form of linear function is
y=ax+b
For finding the slope, use the slope formula.
(4-2)/(-2+1)= 2/-1=-2
We first found a which is -2.
Then insert any point to find the value of b. In this case, I will insert (1,-2).
-2=-2+b
b=-2+2=0
The linear graph is y=-2x
