Hello !
If you mist find the area of the rhombus,you need to calculate the length of the diagonals.
We have the rhombus ABCD.The diagonals are are AC and BD .
<span>Here's a formula to find out the distance between two points in the Cartesian system : (let's take randomly 2 point and their coordinates)
</span>
<span>
M (m₁,m₂) ; N (n₁,n₂) ⇒ MN = \sqrt{ (m_{1} - n_{1})^{2} + (m_{2} - n_{2})^{2} } </span>
Now it's simple to calculate the diagonals :

The area is :
Answer: 60 u²
The representation is below.
Have a nice day :)
Answer:
(a), (d)
Step-by-step explanation:
Use x=2 and evaluate:
(a) y = 5(2) = 10 . . . . (2, 10) is on the graph
(b) y = 8(2) = 16
(c) y = 10 -2 = 8
(d) y = 2 +8 = 10 . . . . (2, 10) is on the graph
Answer:
60
Step-by-step explanation:
The value of n.
Answer:
- 8
Step-by-step explanation:
Given
x² - 64 = 0 ( add 64 to both sides )
x² = 64 ( take the square root of both sides )
x = ±
= ± 8
Solutions are x = 8 and x = - 8
Solution
write the division as a fraction = 12y^4-4y^3 - 6y^2 + 36y - 22 over y-3 multiplied by r over y-3
r ×(2y^4 - 4y^3- 16y^2 + 36y- 22) over (y-3)^2
2ry^4 - 4ry^3 - 16ry^2 + 36ry - 22r over (y-3)^2
