Answer:
m2−20m+72=−3
Step 1: Subtract -3 from both sides.
m2−20m+72−(−3)=−3−(−3)
m2−20m+75=0
Step 2: Factor left side of equation.
(m−5)(m−15)=0
Step 3: Set factors equal to 0.
m−5=0 or m−15=0
m=5 or m=15
Answer:
m=5 or m=15
Point.

This is one of the classic problems of Euclidean geometry.
The angle is determined by three points, we call it A, B, C, with A ≠ C and B ≠ C.
We denote an angle with three points and a symbol ∠. The middle point is always the vertex. We can also give angle names only with vertices. For example, based on the attached image, the angle can be denoted as ∠BAC, or ∠CAB, or ∠A.
Types of Angles
- The acute angle represents an angle whose measure is greater than 0° and less than 90°.
- The right angle is an angle that measures 90° precisely.
- The obtuse angle represents an angle whose measures greater than 90° and less than 180°.
- The straight angle is a line that goes infinitely in both directions and measures 180°. Carefully differentiate from rays that only runs in one direction.
<u>Note:</u>
Undefined terms are the basic figure that is not defined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane.
These key terms cannot be mathematically defined using other known words.
- A point represents a location and has no dimension (size). It is labeled with a capital letter and a dot.
- A line is an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.
- A plane is a flat surface that contains many points and lines. A plane extends infinitely in all four directions. It is two-dimensional. Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.

Answer:
(D) 400
Step-by-step explanation:
It is given that The distance from Earth to the moon is 2.39 × 105 miles, and the distance from Earth to Mercury is 9.2 × 107 miles. Then,
Distance from Earth to Mercury compared to the distance from Earth to the moon is given by:
=
=
≈400.
therefore, option D is correct.
Answer : 1,500 candles.
Explanation : If there are 50 cartons, but only 30 were loaded:
50 - 30 = 20 cartons left to load.
And if there are 75 candles in each carton :
20(75) = 1,500 candles left to load
