Answer:

7+√5/4

Step-by-step explanation:

if that is = a, find the value of a + 1 over a

​Given that a = 3 - √5

a+1/1 = (3-√5)+1/3 - √5

4-√5/3 - √5

Rationalize

4-√5/3 - √5 * 3+√5/3 + √5

= 12 +4√5-3√5-√25/9-5

= 12+√5-5/4

= 7+√5/4

Hence the requred answer is  7+√5/4

6 times the difference of a number and 4 equals 7
Nonamiya [84]
6( x - 4) = 7
6 x - 24 = 7
6 x = 7 + 24
6 x = 31
x = 31/6 

6 ( 31/6 - 4) = 7 
186/6 - 24 = 7
186/6 = 144/6 = 7

42/6 = 7 
7 = 7

(9-4) + 3•8 = 29

Explanation

First you need to apply the PEMDAS rule

Parentheses
Exponents
Multiplication
Division
Addition
Subtract

So when solving the problem you first have to solve what’s in Parentheses first. So (9-4) which would equal 5

Next, according to the PEMDAS rule you’d have to do multiplication next. So 3•8 is equal to 24

And finally, the last step is Addition. After you’ve done the Parentheses and Multiplication you have to add up your answers. 5+24 would be 29

Answer= 29
