The answer is 42 in
the equation is... 3+3+3+3+6+6+6+12=42in
hope this helps!
6w^2 - 21w + 10w - 35
3w( 2w - 7) + 5 ( 2w - 7)
(3w + 5) ( 2w - 7)
This is the factorised form.
Hello,
Let's assume f the age of the father,
s the age of the son.
<span>The age of a father is 2 less than 7 times the age of his son ==> f=7s-2 (1)
</span>
<span>In 3 years, the sum of their ages will be 52 ==>(f+3)+(s+3)=52 (2)
(2)==>f+s+6=52
==>f+s=46 (3)
(3) and (1) ==>7s-2+s=46
==>8s=48
==>s=6
f=46-6=40
</span>
The answer would be -19.8
