Answer: x = -4 ; Angle = 60°
Concept:
The given figure is a triangle with 3 arc signs on each angle. This <u>arc sign </u>stands for the corresponding angles are congruent, which in this question, it shows that all three angles are congruent. Sometimes, if the figure has multiple angles and there are different groupings of congruent angles, then we use different numbers of arcs or symbols.
Solve:
<u>Given information</u>
An angle = 3x + 72
Total measure of angles = 180 (triangle angle sum theorem)
Total number of congruent angles = 3
<u>Given expression</u>
Total measure = Total number of congruent angles × An angle measure
<u>Substitute values into the expression</u>
180 = 3 (3x + 72)
<u>Divide 3 on both sides</u>
180 / 3 = 3 (3x + 72) / 3
60 = 3x + 72
<u>Subtract 72 on both sides</u>
60 - 72 = 3x + 72 - 72
-12 = 3x
<u>Divide 3 on both sides</u>
-12 / 3 = 3x / 3

<u />
<u>Find the angle measure</u>
3x + 72 = 3 (-4) + 72 =

Step-by-step explanation:
=(-2)2+8(-2)+18(-2)+12
=4-16-36+12
=4+52+12
=56+12
=68
OR
=4-16-36+12
= -12-24
= -36
Answer: A = 396 tons
B = 70 tons
Step-by-step explanation:
From the question,
Weight of A + Weight of B = 466
Weight of A - Weight of B = 326
A + B = 466 ......... i
A - B = 326 ..........ii
Subtract equation ii from I
2B = 140
B = 140/2
B = 70 tons
A = 466 - 70
A = 396 tons
In order to build a polynomial we need one or more terms. A term is a number, variable (denoted by a letter) or any combination of numbers and variables held together by multiplication. The following are examples of terms:

Now it might look like one of those involves division but it can be thought of as multiplication by (2/5). When we do this the exponents must be positive.
Polynomials are expressions made up of terms held together by addition and subtraction. Again, the exponents must be positive. Since polynomials are made up of the sum or difference of terms, adding or subtracting polynomials just leads to more polynomials. Here are some examples of Polynomials:

Now let’s consider what happens if we multiply polynomials. As an example we use:

What you might notice is that multiplication will lead us to multiply terms (but multiplying terms gives us more term,as) and also to add or subtract terms but that just gives more polynomials. Therefore multiplication leads to more polynomials.
Finally, we consider division. Here a simple example will do the trick: 2 is a term and x is a term. Let us divide 2 by x. We get:

which is not a polynomial because we have a negative exponent.
Thus, the answer to your question is division. Division of polynomials will not always result in a polynomial.
