Step-by-step explanation:

if you have the answer, why do you ask ?

anyway,

l = length

b = breadth

perimeter = 2×l + 2×b = 30 cm

l = b + 10

now we use this identity in the perimeter equation :

2×(b+10) + 2b = 30

2b + 20 + 2b = 30

4b = 10

b = 2.5 cm

l = b + 10 = 2.5 + 10 = 12.5 cm

Answer:

3

Step-by-step explanation:

Since

3 : 2 = X : 2

Then we know

3/2 = X/2

Multiplying both sides by 2 cancels on the right

2 × (3/2) = (X/2) × 2

2 × (3/2) = X

Then solving for X

X = 2 × (3/2)

X = 3

Therefore

3 : 2 = 3 : 2

You may have noticed that in practice problems related to order, logarithms are usually just "log". As you know from algebra, th
Usimov [2.4K]

Explanation:

A logarithm in one base is a constant multiple of a logarithm in any other base. Any "order of ..." specification does not include the applicable constant multiplier or the smaller order terms that may be required for an exact computation.

The concept of "order of" is similar to the concept of the degree of a polynomial. Knowing the degree of a polynomial tells you something about the "end behavior" as the function argument gets large. The specifics of the scale factor and lower-degree terms become largely irrelevant.
