Answer:

The value of x is 4.

Step-by-step explanation:

Consider a Rectangle ABCD

AB as Top

CD as Bottom

AB = -1 + 4x

CD = 3x + 3

To Find:

x = ?

Solution:

In a Rectangle ABCD

Opposite sides of Rectangle congruent,......Property of Rectangle

AB = CD

Top = Bottom

On substituting we get

-1+4x=3x+3\\\\4x-3x=3+1\\\\x=4\\

Therefore the value of x is 4.

Please help me<br><br> Determine the value of base b if (152)b = 0x6A. Please show all steps.
egoroff_w [7]

Answer:

The value of b is, 8

Step-by-step explanation:

To determine the value of b:

Given:

(152)_b = 0x6A               ....[1]

Since, 0x6A represents the hexadecimal form.

To convert this hexadecimal form into decimal form:

(6A)_{16}= (6 \times 16^1)+(A \times 16^0)=(6 \times 16)+(10 \times 1) =96+10 = 106

⇒0x6A=106(decimal form)

Now we have to convert this decimal form into octal

8  |  106

8   |  13   | 2

    |   1    |  5

        1

Then, the octal form we get, (152)_8

Substitute this in [1] we have;

(152)_b = (152)_8

On comparing both sides we have;

b = 8

Therefore, the value of b is, 8
