Answer:
3.183.10^7
Step-by-step explanation:
Answer: 70
Step-by-step explanation:
10 x 7
Answer:
I'll setup the problem and you can do the calculations
Step-by-step explanation:
Total length of straw - L
Length of piece 1 - x
Length of piece 2 - y
Length of piece 3 - z
What's given and the answer to (i)
y = x - 3
z = 2x
(ii) L = x + y + z = x + x - 3 + 2x
L = 4x-3
(iii) x = (21+3)/4 = 24/4
leaving you to calculate x
then substitute x into expressions for y & z above and you will have the answer

Answer:
Final answer is
.
Step-by-step explanation:
Given expression is
.
Now we need to smplify the given expression
.
So begin with factoring 20 into two parts so that one part is perfect square number.
![\sqrt{20y^8}](https://tex.z-dn.net/?f=%5Csqrt%7B20y%5E8%7D)
![=\sqrt{4 \times 5y^8}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B4%20%5Ctimes%205y%5E8%7D)
![=\sqrt{4 y^8} \times \sqrt{5}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B4%20y%5E8%7D%20%5Ctimes%20%5Csqrt%7B5%7D)
![=2y^4 \times \sqrt{5}](https://tex.z-dn.net/?f=%3D2y%5E4%20%5Ctimes%20%5Csqrt%7B5%7D)
Hence final answer is
