We can do this using Pythagorus,,,
87.5*2 - 52.5*2 = AB*2
4900 = AB*2
70 = AB
The total cost for peaches is $0.40 you get that by (0.5)(0.80) as for oranges (0.7)(.90)=$0.63 so $0.40+$0.63=$1.03
Answer:
Step-by-step explanation:
#1 Synthetic method
- 2x³ + x² - 2x - 4 ÷ x + 1 = 2x² - x - 1 rem 3
--------------------------------------
x + 1 | 2x³ + x² - 2x + 4
---------------------------------
-1 | 2 1 -2 4
<u>| - 2 1 1 </u>
2 - 1 - 1 3
#2 Long division
- 3x³ - 5x² - 26x - 8 ÷ 3x + 1 = x² - 2x - 8
--------------------------------------
3x³ - 5x² - 26x - 8 <u>| 3x + 1</u> = x² - 2x - 8
<u>3x³ + x²</u>
-6x² - 26x
<u>-6x² - 2x</u>
- 24x - 8
<u>- 24x - 8</u>

Area Of Rectangle
= 2 length × 2 width
= 2 l + 2 w
l = 2 w -3................equation (i)
2 l + 2 w = 42..........equation (ii)
2(2 w -3) + 2 w =42
4 w - 6 + 2 w = 42
4 w + 2 w = 42 + 6
6 w = 48
w =8
l = 2 w - 3
l = 2×8 - 3
l = 13
Length = 13
Width = 8
