azamat3 years ago
5 0

Step-by-step explanation:

Some of the property of log are as follows :

1. \text{log a}-\text{log b}=\text{log} \dfrac{\text{a}}{\text{b}}

2. \text{log a}+\text{log b}=\text{log}(a{\cdot} b)

3. \text{log}a^n=n\ \text{log} a

Now coming to question,

(a) \text{log 5}-\text{log 8}=\text{log} \dfrac{\text{5}}{\text{8}} (using property 1)

(b) \text{log 1}+\text{log 3}=\text{log}(1{\cdot} 3)=\text{log} 3 (using property 2)

(c) \text{log} 4=\text{log} 2^2=2\ \text{log} 2 (using property 3)

Hence, this is the required solution.

The width of a rectangle is 1.9 feet. The perimeter is 7.4 feet. What is the length?
dimaraw [331]

Answer:2.8 feet

Step-by-step explanation:

length(l)=?

breadth(b)= 1.9 feet

perimeter(p)=7.4 feet

we know,

p=2(l+b)

7.4=2(l+1.9)

7.4=2l+3.8

2l=7.4-3.8 (changing side and bringing 3.8 to 7.4 it gets -3.8)

l=3.6/2

l=2.8 feet

Hence,length is 2.8 feet

Solve for c.<br><br> 2(c +1) = 10
coldgirl [10]

Answer:

c=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(c+1)=10

(2)(c)+(2)(1)=10(Distribute)

2c+2=10

Step 2: Subtract 2 from both sides.

2c+2−2=10−2

2c=8

Step 3: Divide both sides by 2.

2c

2 = 8

2

c=4
