Length= 2*width
area=l*w=2*width*width=2*width^2
area+160=(2*width+1)*(width+1)
A+160=2w^2+2w+w+1
A+160=2w^2+3w+1
putting value of a
2w^2+160=2w^2+3w+1
160=3w+1
w=53m
l=106m
Answer:
- Equal midpoints of AC and BC.
- The product of the slopes of the diagonals AC and DB is -1.
Step-by-step explanation:
1. Plot the given points, as you can see in the graph attached.
2. Calculate the midpoint of AC and DB:

Therefore, the midpoint of AC and DB are equal.
3. Calculte the slope of the diagonals AC and DB:

4. Multiply the slopes of the diagonals:
(AC and DB are perpendicular)
Answer:
b. 6¹⁰ / 7⁶
Step-by-step explanation:
(6⁵/7³)²
6 × 6 × 6 × 6 × 6 = 7776
7 × 7 × 7 = 343
(7776/343)²
7776²/343²
7776 × 7776 = <u>60.466.176</u>
343 × 343 = <u>117.649</u>
6¹⁰/7⁶
6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 = 60.466.176
7 × 7 × 7 × 7 × 7 × 7 = 117.649
6¹⁰ = 7776²
7⁶ = 343²
= <u>b</u><u>.</u><u> 6¹⁰ / 7⁶</u>
