Step-by-step explanation:

An investment club invested part of $8000 at 10% annual interest the rest at 12%. If the annual income from these investments is
marta [7]
Let x be the amount invested  at 10%
so the amount invested at 12 % =  (8000-x)
   0.1x + 0.12(8000-x) = 900
   0.1x - 0.12x = 900- 960
   0.02x = 60
     x   =  3000      @ 10%
              8000 - 3000    =    5000     @ 12%

<h3>GCF for given expression is:</h3>

GCF = 5(x+7)^2

<em><u>Solution:</u></em>

Given that,

We have to find the greatest common factor

5(x+7)^4\\\\35(x+7)^2\\\\15(x+7)^3

First find the GCF of numbers 5, 35 and 15

<em><u>Find the GCF of 5, 35 and 15</u></em>

The factors of 5 are: 1, 5

The factors of 15 are: 1, 3, 5, 15

The factors of 35 are: 1, 5, 7, 35

Then the greatest common factor is 5

Now find the GCF of variables

(x+7)^4\\\\(x+7)^2\\\\(x+7)^3

Here, the common factor is (x+7)^2

<em><u>Thus, GCF for given expression is:</u></em>

GCF = 5(x+7)^2
