Answer:
The Index
Step-by-step explanation:
A radical expression is composed of three parts:
The Radicand - The number or term under the horizontal bar of the radical symbol.
Radical Symbol - The Radical Symbol √
Index - The number near the "check" part of the radical symbol.
In the given expression, 4 is the index. We are supposed to find the 4th root of x to the third power.
Hope this helps.
Answer:
i have no clue ..
Step-by-step explanation:
By reducing!
sorry lol!!!!
p = r - c |add c to both sides
p + c = r - c + c
r = p + c
#1 alright so if the ratio is 5:4 adding them together is 9 but we want 36 as the perimeter sooo
36/9=4
So multiply both the 5 and the 4 makes....
20:16
The 20 and 16 show the total side of the length Andy width so we need to divide them by two so...
(20/2):(16/2)=10:8 so the width would be 8
Check:10(2)+8(2)=20+16=36 yay on to the next one!
#2 ok let's say the length is x, that means the width would be x-5 so the perimeter of that would be 4x-10. Sooo...
4x-10=54 || 4x=54+10 || 4x=64 || x= 16
So the length is 16 while the width is 11. Let's check in case.
16(2)+11(2)=32+22=54 yup :D
