Answer:
16 marbles.
Step-by-step explanation:
Since your friend is blindfolded the only actual way for him to be completely sure that they picked out all 6 black marbles would be to pick out all of the marbles until none are left. As long as there is even one marble in the bag then your friend will still not be sure which color it is due to being blindfolded. Therefore, under these circumstances the answer would be 16 marbles.
For the first one, find a number in which, when factored, will give you 4.
x² + 4x + 4
x 2
x 2
(x + 2)(x+ 2)
4 is your best answer
2. x² - 10x + ____
Same for this question. Find a number that, when factored, will give you -10
-100
x² - 10x + 25
x - 5
x -5
(x - 5)(x - 5)
25 is your answer
hope this helps
3x+y=163 2x+3y=174
it should be like this {: and each point is one.
Answer:
y=4x+3
Step-by-step explanation:
use point slope form
(y-y₁)=m(x-x₁)
fill in
y-5=4(x-(-2))
solve
y-5=4x+8
y=4x+8-5
y=4x+3

Step-by-step explanation:</h2>
A prism is a solid object having two identical bases, hence the same cross section along the length. Prism are called after the name of their base. On the other hand, a rectangular prism is a solid whose base is a rectangle. Multiplying the three dimensions of a rectangular prism: length, width and height, gives us the volume of a prism:
From the statement of the problem we know:
So:
Since we can't have negative distance, the only valid option is
