Simplify this expression. 7ײ+9ײ-ײ

Mathematics
1 answer:
guapka [62]2 years ago
4 0

Step-by-step explanation:

7x² + 9x² - x²

when you wrote the expression you used the "multiplication ×" and not "x".

anyway, when you have terms of the same variable of the same exponent, then the combination variable and exponent become an item. and the same items can simply be added in an expression.

this is similar to

7 apples + 9 apples - 1 apple

what would you do there ?

see ?

and the same we are doing now for the given expression : we are adding the terms up :

7x² + 9x² - x² = (7 + 9 - 1)x² = 15x²

and in the middle I gave you even the reason why we can do that.

please, let me know, if this is still unclear.

Find the value of x (URGENT/GIVING BRAINLIEST)
alexira [117]

Answer:

D. 24

Step-by-step explanation:

Angles are the same, so 84 = 3x.

To get x alone, you divide 3 by both sides.

84/3 = 24

24 = x.

Find measure.<br> m ∠ 5
jeka57 [31]

Measure of angle 5 i.e. m∠5 = 50°

<h3>What is measurement of an angle ?</h3>

The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.

<h3>How to  find angle measurement ?</h3>

As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.

In the question,

Let given angle is ∠8.

Given, ∠8 = 50°

Now, according to vertical angle property

∠5 = ∠8

therefore, ∠5 = 50°

Thus, m∠5 = 50°
