If p q r is prime numbers such that pq+r=73, what is the least possible value of p+q+r
Jobisdone [24]
The answer to this question would be: p+q+r = 2 + 17 + 39= 58

In this question, p q r is a prime number. Most of the prime number is an odd number. If p q r all odd number, it wouldn't be possible to get 73 since
odd x odd + odd= odd + odd = even
Since 73 is an odd number, it is clear that one of the p q r needs to be an even number. 

There is only one odd prime number which is 2. If you put 2 in the r the result would be:
pq+2= 73
pq= 71
There will be no solution for pq since 71 is prime number. That mean 2 must be either p or q. Let say that 2 is p, then the equation would be: 2q + r= 73

The least possible value of p+q+r would be achieved by founding the highest q since its coefficient is 2 times r. Maximum q would be 73/2= 36.5 so you can try backward from that. Since q= 31, q=29, q=23 and q=19 wouldn't result in a prime number r, the least result would be q=17
r= 73-2q
r= 73- 2(17)
r= 73-34=39

p+q+r = 2 + 17 + 39= 58

<u>Answer</u>

48


<u>Explanation</u>

The product of the secant and the extension of the chord is normally equivalent to square of the tangent.

From the diagram given,

The length of the secant = 2+6

                                          = 8

Length of the extension of the chord = 6

length of the tangent = x

∴ x² = 8 × 6

      = 48

5(x+7)+2 = 4(x - 1) + 1
Nadya [2.5K]

Answer:

x = -40

Step-by-step explanation:

First we distribute

5x + 35 + 2 = 4x - 4 + 1

Collect like terms

5x + 37 = 4x - 3

Subtract 37 from both sides

5x = 4x - 40

Subtract 4x from both sides

1x = -40 OR x = -40
