Mrs. Ishimitsu is installing a rubber bumper around the edge of her coffee table. The dimensions of the rectangular table are (2

ollegr [7]

Answer:

$2x^2+8x-30$ represents the total perimeter of the table, and if x = 3 the lentgh of entire rubber bumper is 12 feet.

Step-by-step explanation:

Perimeter is defined as the sum of sides.

For a rectangle having dimension length 'L' and breadth 'B' Since, rectangle has two sides equal.

Perimeter of rectangle = 2 ( length + breadth )

Here, given rectangle has dimension

Length = $2x^2-16$ and breadth = $-x^2+4x+1$

Thus, perimeter of rectangle = $2(2x^2-16+(-x^2+4x+1))$

$=2(2x^2-16-x^2+4x+1)$

$=2(x^2+4x-15)$

$=2x^2+8x-30$

Thus, perimeter of rectangle is $2x^2+8x-30$ ........(1)

Perimeter of rectangle , when x = 3,

Put x= 3 in (1) ,

$2x^2+8x-30\Rightarrow 2(3)^2+8(3)-30 \Rightarrow 18+24-30=12$

Thus, $2x^2+8x-30$ represents the total perimeter of the table, and if x = 3 the lentgh of entire rubber bumper is 12 feet.

Q ,# 18 help to resolve please

Sati [7]

Answer: 120

"A analog clock is diveded up into 12 sectors, based on the numbers 1-12. one sector represents 30 degrees (360/12=30). if the hour hand is directly on the 10, and the minute hand is on the 2, that means there are 4 sectors of 30 degree between then, thus they are 120 degree apart (30*4=120)."

Why is 1/2 not useful as a benchmark to compare 5/8 and 9/10?

pentagon [3]

1/2 would not be a useful benchmark to compare these 2 fractions because both of them are greater than half. The benchmark fraction 1/2 is most useful when one fraction is less than half and the other more than 1/2. 5/8 is more than 4/8(1/2), and 9/10 is more than 5/10(1/2).

Please help me with this question! i will give brainiest if correct! (if you show me how to lol i have no idea how)

Nitella [24]

Answer:

y(2x² + y) / x(5y² - 6x)

Step-by-step explanation:

Simplify the numerator:

1/x² + 2/y =
y/(x²y) + 2x²/(x²y) =
(2x² + y)/(x²y)

Simplify the denominator:

5/x - 6/y² =
5y²/(xy²) - 6x/(xy²) =
(5y² - 6x) / (xy²)

Simplify the fraction:

(2x² + y)/(x²y) ÷ (5y² - 6x) / (xy²) =
(2x² + y)/(x²y) × xy² / (5y² - 6x) =
y(2x² + y) / x(5y² - 6x)
