Answer:
=> Apply law of cosine
=> input value
=> simplify
=> calulcation
=> apply rule: Distance must be greater than 0
which is about 14.51828
If the width is 28 inches, then divide that by 4 and you get 7. You multiply that by 5 to get the length. That would be 35. Just to check, you know that the width 28 and length 35 are in ratio 4:5 if you divide by 7. The perimeter would be 2(35+28)=63*2=126. So the perimeter is 126. The area would be 35*28 which is 980. To sum up, the answers are as follows.
Length: 35 in
Perimeter: 126 in
Area: 980 inches squared.
Answer:
5) A
6) A
Step-by-step explanation:
5) With the sides of the rectangle being dilated, multiply the side lengths by the scale factor
7.5(2.2) and 3(2.2)
16.5 and 6.6
6) Multiply the coordinates by the scale factor as dilations work as (x, y) -> (kx, ky)

Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form: where m is the slope and b is the y-intercept (the value of y when x is 0)
- Parallel lines always have the same slopes
<u>1) Determine the slope (m)</u>
The given line has a slope of -2. Because parallel lines always have equal slopes, we know that the line parallel to this would also have a slope of -2. Plug this into :
<u>2) Determine the y-intercept (b)</u>
Plug in the given point (2,4) to solve for b
Add 4 to both sides to isolate b
Therefore, the y-intercept of the line is 8. Plug this back into :
I hope this helps!
