Answer:
(3x+4)(3x+4) is factor of given expression.
B is correct.
Step-by-step explanation:
We are given an expression ![9x^2+24x+16](https://tex.z-dn.net/?f=9x%5E2%2B24x%2B16)
Formula: ![a^2+2ab+b^2=(a+b)^2](https://tex.z-dn.net/?f=a%5E2%2B2ab%2Bb%5E2%3D%28a%2Bb%29%5E2)
First we write each term as perfect square as formula.
![\Rightarrow 9x^2+24x+16](https://tex.z-dn.net/?f=%5CRightarrow%209x%5E2%2B24x%2B16)
![\Rightarrow (3x)^2+2\cdot 3x\cdot 4+4^2](https://tex.z-dn.net/?f=%5CRightarrow%20%283x%29%5E2%2B2%5Ccdot%203x%5Ccdot%204%2B4%5E2)
Using formula , a=3x and b=4
![\therefore (3x)^2+2\cdot 3x\cdot 4+4^2=(3x+4)^2](https://tex.z-dn.net/?f=%5Ctherefore%20%283x%29%5E2%2B2%5Ccdot%203x%5Ccdot%204%2B4%5E2%3D%283x%2B4%29%5E2)
Now we write same number two times.
Hence, (3x+4)(3x+4) is factor of given expression.

Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
If i = √-1, then i^2 = -1.
You will have 4 groups of 10 and then 6 single toys
A)
2, 4, 6, 8, *10
The fifth row contains 10 cans.
----------------------------------------------------
b)
2+4+6+8+10+12+14+16+18+20=110
-----------------------------------------------------
c)
2*Row=Number Of Cans
When Row=1, Number Of Cans=2.
When Row=5, Number Of Cans=10.
When Row=10, Number Of Cans=20.
