Ten million ten thousand four hundred sixty eight
There's only information to answer question C.
We can only know that 32 marbles were chosen. (yellow and black)
Why?
To answer the first two questions (a and b), we need to know the total number of marbles, so, we can only answer the last question (c).
We know that 7/10 of the 20 yellow marbles were chosen.
So, calculating we have:

Also, we know that 18 black marbles were chosen, so, the total of marbles chosen is equal to 32 (yellow marbles and black marbles)

Have a nice day!
Answer:
Step-by-step explanation:
Circum center of a right isosceles triangle is located on the midpoint of the hypotenuse.
Circumcenter of a triangle is point where the perpendicular bisectors of the sides of triangles intersect. Keeping this as a center, you can draw a circle & all the three vertices of the triangle lies on the circumference of the circle. Circumcenter is equal distance from the vertices of the triangle.
For acute triangle, circumcencenter will be inside the triangle.
For obtuse triangle, circumcenter will be outised the triangle.
Answer:
Solution:
Step 1: Remove parentheses by multiplying factors.
= (x * x) + (1 * x) + (2 * x) + (2 * 1)
Step 2: Combine like terms by adding coefficients.
(x * x) = x2
(1 * x) = 1x
(2* x) = 2x
Step 3: Combine the constants.
(2 * 1) = 2
Step 4: Therefore, Simplifying Algebraic Expression is solved as
= x2 + 3x + 2.
