A) Both terms contain x, so they can be combined. -25 + 36 = 11 therefore -25x + 36x = 11x
B) 7s and 3s both contain s, so they can be combined, but the 3 cannot be combined with them as it does not contain an s. 7 - 3 = 4 therefore 7s - 3s = 4s. The 3 stays on its own as it cannot be combined, therefore the answer is 4s + 3
C) 12x and 2x contain x, so they can be combined, but the 11 cannot be combined with them as it does not contain an x. 12 - 2 = 10 therefore 12x - 2x = 10x. The 11 stays on its own as it cannot be combined, therefore the answer is 10x - 11

Mm I think it’s the 3rd chart
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
