-4 is not an inequality, and a bare naked number doesn't have a graph.
Answer:
perimeter of a rectangular swimming pool is 154 m. Its length is ... 2x + 3x + 3 + 4x + 8 = 74. => 9x + 11 = 74. => 9x = 74 – 11. => 9x = 63 ... Solve the following equations and check your results: 2x/3 + 1 = 7x/15 + 3.
X-y,
Cause X could be 1 and y could be 10.

Answer:
The diameter of the circle is 19 m
Step-by-step explanation:
The formula of the area of a circle is A = π r², where r is its radius
<em>To find the diameter from the area of the circle equate the formula of the area by the value of the area to find r, then multiply r by 2 because the diameter of a circle is equal twice its radius</em>
<em />
∵ The area of the circle is 90.25 π m²
∵ A = π r²
- Equate A by 90.25 π
∴ π r² = 90.25 π
- Divide both sides by π
∴ r² = 90.25
- Take √ for both sides
∴ r = 9.5
∵ The diameter of a circle is twice its radius
∴ d = 2 r
- Substitute r by 9.5
∴ d = 2(9.5)
∴ d = 19
The diameter of the circle is 19 m
