In the given diagram, the value of the dashed side of rhombus OABC is 5
<h3>Distance between two points </h3>
From the question, we are to determine the length of the dashed line (OA), in rhombus OABC
In the diagram, we can observe that the length of OA is the distance between point A and the origin (O).
Using the formula for calculating distance between two points,
d =√[(x₂-x₁)² + (y₂-y₁)²]
In the diagram,
The coordinate of the origin is (0, 0)
The coordinate of point A is (3, 4)
Thus,
x₁ = 0
x₂ = 3
y₁ = 0
y₂ = 4
Putting the parameters into the formula, we get
OA =√[(3-0)² + (4-0)²]
OA =√(3² + 4²)
OA =√(9+16)
∴ OA =√25
OA = 5
Hence, in the given diagram, the value of the dashed side of rhombus OABC is 5

Answer:
-3
Step-by-step explanation:
A calculator is useful for this.

Inside parentheses, we evaluate the multiplication first.
−1⋅[(3−4⋅7)÷5]−2⋅24÷6
= −1⋅[(3−28)÷5]−2⋅24÷6
Then the addition inside parentheses.
= −1⋅[−25÷5]−2⋅24÷6
Now, we do the division inside parentheses.
= −1⋅[−5]−2⋅24÷6
Then we do the multiplication and division left to right.
= 5−48÷6
= 5−8
Finally, we do the sum.
= -3
