The area of rectangle ABCD is 28 cm^2

Mathematics
1 answer:
Sonbull [250]2 years ago
8 0

The length of AB is (x + 4) cm and the values of a and be are a = 10, b = 4

A rectangle is a quadrilateral in which opposite sides are equal and parallel to each other. The area of a rectangle is:

Area = length * width

From the image:

Length of AB = x + 4

Length of BC = x + 6

The area of rectangle ABCD = Length of AB * Length of BC

28 = (x + 4)(x + 6)

x² + 10x + 24 = 28

x² + 10x = 4

Comparing with x² + ax = b gives:

a = 10, b = 4

Therefore the length of AB is (x + 4) cm and the values of a and be are a = 10, b = 4

Which of the following numbers is proportional to 84/108?
lara [203]

Proportional numbers are numbers with the same equivalent ratio

98/126 is proportional to 84/108

The number is given as:

Number = \frac{84}{108}

Reduce fraction to the lowest term

Number = \frac{7}{9}

Reduce 86/110 to the lowest term

Number = \frac{86}{110}

Divide by 2/2

Number = \frac{43}{55}

43/55 is not equivalent to 7/9

Reduce 98/126 to the lowest term

Number = \frac{98}{126}

Divide by 14/14

Number = \frac{7}{9}

7/9 is equivalent to 7/9.

Hence, 98/126 is proportional to 84/108

Snowcat [4.5K]

Answer:

3\frac{7}{17}

Step-by-step explanation:

\frac{(x + 6)}{(x - 4)}  =  - 16 \\  \\ x + 6 =  - 16(x - 4) \\ x + 6 =  - 16x + 64 \\ x + 16x = 64 - 6 \\ 17x = 58 \\ x =  \frac{58}{17}  \\ x =  3\frac{7}{17}  \\

4. Ratio scale

  • Consist of the features of nominal, ordinal, and interval measures but in includes a "true zero" point.

For example : Age.
