Which of the following solves the proportion 3/8 = x/24?

2 answers:

3 0

The answer is 9. If you multiply the denominator of the first fraction by 3, you get the denominator of the second fraction. To find the top number of the second fraction, you also have to multiply the numerator by 3. Therefore the answer would be 9.

24 / 8 = 3

This shows that 8 was multiplied by 3 to get 24.

3 * 3 = 9

Now, we know that 9 solves the proportion. (x = 9)

To check, we can simplify 9/24.

9/24 → 3/8

Hope This Helped! Good Luck!

The playground at a park is shaped like a trapezoid the dimensions what is the area of the playground in square feet

Maru [420]

Answer:

$Area = 1560ft^2$

Step-by-step explanation:

Given

See attachment for playground

Required

Determine the area

The playground is a trapezoid. So;

$Area = \frac{1}{2}(Sum\ parallel\ sides) * Height$

From the attachment, the parallel sides are: 68ft and 36ft

The height is: 30ft

So, the area is:

$Area = \frac{1}{2}(68ft + 36ft) * 30ft$

$Area = \frac{1}{2}(104ft) * 30ft$

$Area = 52ft * 30ft$

$Area = 1560ft^2$

sladkih [1.3K]

Answer:

2x(2x²+x+1)

Dtep-by-step explanation:

f(x) = 9x³+2x²-5x+4

g(x) = 5x³-7x+4

f(x) - g(x)

= 9x³+2x²-5x+4 - (5x³-7x+4)

= 9x³+2x²-5x+4-5x³+7x-5

= 4x³+2x²+2x

= 2x(2x²+x+1)
