An equation is also called a number sentence. Explain how an equation in mathematics is like a sentence in English.​
timurjin [86]

Answer:

 A number sentence is a mathematical sentence, made up of numbers and signs.The expressions given in  examples indicate equality or inequality.A number sentence can use any of the mathematical operations from addition, subtraction, multiplication to division. Symbols used in any number sentence vary depending upon what they indicate.Number sentences can be true or they may not be true.

For example:

10 + 5 = 15. Here we are using the = sign which indicates a balance of both sides.

However, there could also be number sentences which say:

12 + 6 = 9 is not true, but 12 + 6 = 18 is true.

Therefore, a number sentence does not necessarily have to be true. However, every number sentence gives us information, and based on the information provided; it is possible to change the statement from false to true.

So, a number sentence contains numbers, mathematical operations, equal to or inequality sign and a number after the equality or inequality sign. If we remove any of these components, it will no longer be a number sentence.

Two opposite sides of a square with length x are increased by 3 units each and the other two opposite sides are decreased by 3 u
SCORPION-xisa [38]
All four sides of the original square have length s.

Adding 3 to s results in s+3, the length of the resulting rectangle.
Subtracting 3 from s results in s-3, the width of the rectangle.

The area of the rectangle is (s+3)(s-3) = s^2 - 9 = 27,  

and therefore s^2 = 36, and s = 6 square units.

The equation of the graphed line in point-slope form is ____
Vesnalui [34]
Hello : 
The equation of the graphed line in point-slope form is  : <span>y-0=-3/5(x-3)
because ; when : x=3  y=0  passes by : (3,0)
when : x = -2  y = 3  passes by : (-2, 3)

</span>and its equation in slope-intercept form is : <span>y= -3/5x+9/5
because : </span> y-0=-3/5(x-3)     : y = -3/5x +9/5

Use ΔABC shown below to answer the question that follows:
topjm [15]

Answer:

The correct options are a and b.

Step-by-step explanation:

It is given that triangle ABC with segment AD drawn from vertex A and intersecting side BC.

Two triangle are called similar triangle if their corresponding sides are proportional or the corresponding interior angle are same.

To prove ΔABC and ΔDBA are similar, we have to prove that corresponding interior angles of both triangle as same.

If segment AD is an altitude of ΔABC, then angle ADB is a right angle.

\angle BDA=90^{\circ}

The opposite angle of hypotenuse is right angle. If segment CB is a hypotenuse, then angle ABC is a right angle.

\angle BAC=90^{\circ}

In triangle ΔABC and ΔDBA

\angle ABC\cong \angle DBA              (Reflexive property)

\angle BAC\cong \angle BDA              (Right angles)

By AA rule of similarity ΔABC and ΔDBA are similar.

Therefore correct options are a and b.
