HELP!! MARKING BRAINLIEST

Mathematics
1 answer:
Zarrin [17]2 years ago
4 0

Step-by-step explanation:

perimeter is the sum of all 4 sides.

so,

5x²y + 3y² + 5x²y + 3y² = 2×5x²y + 2× 3y² = 10x²y + 6y²

the area is

length × width

so,

5x²y × 3y² = 15x²y³

there is no way to define a specific number solution for x and y, as there is no "anchor" information like what is the perimeter and the area in numbers. only from that could we then calculate back what x and y are.

The picture shows a circular clock face.
marysya [2.9K]

Answer:

[C] 25π square inches

Step-by-step explanation:

<u><em>Given that:</em></u>

<em>the long hand of the clock is about 5 inches long.</em>

<u><em>To Find:</em></u>

<em>What is the approximate area of the clock face?</em>

<u><em>Solve:</em></u>

<em>Formula - </em><em>A =πr²</em>

<em>Note that;</em>

<em>π = 3.14 (about)</em>

<em>Radius - 5 inches</em>

<em>A =πr²</em>

<em>A = 3.14(5)²</em>

<em>A = 3.14(25)</em>

<em>A = 78.5</em>

<em>Now let see the answer choices:</em>

<em>A.  5π square inches                     ≈   5(3.14) = 15.7</em>

<em>B. 10 π square inches                    ≈  10(3.14) = 31.4</em>

<em>C. 25 π square inches                    ≈  25(3.14) = 78.5</em>

<em>D. 100 π square inches                    ≈ 100(3.14) = 314</em>

<em />

<em>Hence, the answer is [C] 25 π square inches </em>

<em />
