Your answer would be 17cm.
Because two sides are equal, we can label these two sides x, and the base y, and since the perimeter is 71cm, we can then write the equation 2x + y = 71.
Then we apply the changes made to our sides, so the two equal sides would become x - 4, and the base would become y + 6. We can now set these equal to each other as it states that all sides are equal when this change occurs.
Now we have a pair of simultaneous equations that we can solve with substitution firstly by rearranging the equation x - 4 = y + 6 to get x:
x - 4 = y + 6
+ 4
x = y + 10
Now we can substitute (y + 10) as x into the equation 2x + y = 71 :
2(y + 10) + y = 71
2y + 20 + y = 71
3y + 20 = 71
- 20
3y = 51
÷ 3
y = 17
I hope this helps!
10m-6... Brianliest would be greatly appreciated and would help
Composing functions just means to feed the ouput of the inner one as the input for the outer one.
So, the following writings are equivalent:
Using the second form, we can see that the first thing to do is to compute 
, which is given:
This means that we can update the fomula:
So, now we have to compute 
. Given 
, we know that 
doubles the input and adds one. In this case, the input is 
, so we have to double this and add one:
So, we have
Similarly, from 
, we understand that 
just adds 3 to the input. In this case, the input is 
, so we'll add 3 to this quantity:
So, we finally have
