Answer: R = (4, 5)
Step-by-step explanation: Midpoint is simply the center of a line. So, the equation for it is ((x1+x2)/2, (y1+y2)/2). Hence for this,
x coordinate- (6+x)/2=5
x=4
y coordinates- (9+y)/2=7
y=5
And therefore R is (4, 5)
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:
A
Step-by-step explanation:
The diagonals of a rectangle are congruent and bisect each other, so
AC = BD
2AG = 2DG, that is
AG = DG, substitute values
- 7y + 5 = 2y + 68 ( subtract 2y from both sides )
- 9y + 5 = 68 ( subtract 5 from both sides )
-9y = 63 ( divide both sides by - 9 )
y = - 7
Hence
BD = 2(2y + 68)
= 4y + 136
= (4 × - 7) + 136
= - 28 + 136
= 108 → A

Answer:
100 + (5 * 60) = 400
400 - (2*120) = 160
end position = 160
