Answer:

B.)7√5

Step-by-step explanation:

2√5+ 5√5 = 7√5

we simply let √5  = x

therefore;

2√5+ 5√5 = 2x + 5x

2x + 5x = 7x

but x = √5

2√5+ 5√5 = 7√5

Find two consecutive even integers such that the sum of the larger and three times the smaller is 234
viva [34]

Represent even numbers as "2n" since each is a multiple of 2.

Represent odd numbers as "2n+1" since each is one more than an even.

-----------------

Your problem:

smaller # : 2n

larger #: 2n+2

-------------------

EQUATION:

2n+2 + 3(2n) = 234

8n = 232

n = 29

---------

smaller = 2*29 = 58

larger = 2n+2 = 60
