The GCF is 6, since both 18 and 6 are divisible by six.
18x+6y
Pull out a six to factor
6(3x+y)
(9x^2+10x+c) = (3x+b)^2
= 9x^2 + 6b x+ b^2
1) 6b= 10
b+ 5/3
2) c=b^2
c= (5/3) ^2
c= 25/9
(9x^2+10x+25/9)=(3x+5/3)^2
I hope this helps:)
The common multiple of 12 and 20 is 60.
You've got to multiply the first one by 5 and the second by 3.
5*5= 25
This therefore becomes 25/60
The second becomes 3*3= 9
This becomes 9/60
As you're subtracting, you only subtract the numerators.
25-9= 16
Therefore, the answer is 16/60 which can be simplified to 4/10 or 2/5
Hope this helps :)
To solve this problem we are going to use the simple interest formula:
where
is the sum of the <span>interest and the principal
</span>
is the principal
is the interest rate in decimal form
is the time in years
<span>
We know for our problem that </span>
,
, and
. Now, let
represents our interest rate. To express the interest rate in decimal form, we are going to divide the rate by 100%:
.
Now that we have all the values we need, lets replace them in our simple interest formula to find the interest rate:
We can conclude that the interest rate of your cousin's loan was 8%.
Answer:
22cm
Step-by-step explanation:
7+3=10
10+8=18
18+4=22
