Answer:
B. ab+ac=d
Step-by-step explanation:
Carbon dioxide from the atmosphere dissolves in the surface waters of the ocean. Some of the carbon dioxide stays as dissolved gas, but much of it gets turned into other things. Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter.
The missing factor in the equation is -21
<h3>What is a distributive factor?</h3>
The Distributive Property introduces the multiplication operator an existing mathematical statement that involves the addition operator.
From the complete question, the equation is given as:

Where x represents the missing factor.
So, we have:

Remove brackets

Collect like terms

Evaluate the like terms

Divide both sides by -1

Hence, the missing factor in the equation is -21

Answer:

Step-by-step explanation:
Step 1: Identity the radius.
Since O is the center of the circle, and C and E lie on the circumference, OC and OE are the radii of the circle and thus,
OC=OE.
Step 2: Consider the rectangle.
All diagonals in a rectangle are congruent so this means
DB= OC ( OC is also a diagonal).
Thus, OC= 10 units.
Step 3: Analyze
So this means OE is also 10 units as well.
Since we know the length of the radius, Use the area of circle,


So the area of a circle is 100 pi.
Answer:
80%
Step-by-step explanation:
There are five separate points. One represents students who made more than 13 baskets. The other four represent students who made 13 or less baskets. 4/5 (four-fifths) is equal to 80%.
