Answer:
Given that in the jar, navy beans and white beans in a ratio of 1:9. Let the amount of navy beans be x.
Then, the amount of white beans in the jar is 9x.
Given that amount of navy beans is x=90
Total amount of beans in the jar is x+9x=10x=10+90=900
So the ratio is 1:9
Step-by-step explanation:
Answer:
(a+4)(a-4)=a²-4² ITS LIKE THIS BECAUSE ITS AN IDENTITY,
⇒a²-16
Even when we solve it by the regular method of solving polynomials we get a²-16 as answer as there and thats the proof for the identity.
(a+b)(a-b)=a(a-4)+4(a-4)
⇒a²-4a+4a-16
⇒a²-16[NOTE:-4a+4a=0]
Thus we can see that a²-16 is the answer we get when we try to solve it by regular polynomial solution tooo.
And a²-16 is the polynomial from which we get (a+4)(a-4)



Answer: A.
Another way to solve by factoring 1/4.

![= [\dfrac{1}{4}(A + B)]^2](https://tex.z-dn.net/?f=%20%3D%20%5B%5Cdfrac%7B1%7D%7B4%7D%28A%20%2B%20B%29%5D%5E2%20)




Answer:
64 cm
Step-by-step explanation:
To find the volume, you should multiply length by width, and then by height or 4 x 4 = 16, then 16 x 4 = 64
