Answer:
x = 35
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Geometry</u>
- Definition of a Line: A line is 180°
Step-by-step explanation:
<u>Step 1: Set up equation</u>
40° + (2x + 30)° + 40° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 2x + 110 = 180
- Subtract 110 on both sides: 2x = 70
- Divide 2 on both sides: x = 35
Answer:
-6m^4-m^3
Step-by-step explanation:
First you move the parenthesis then you group the like terms after you group the like terms you get
which is adding the similar elements and after you add similar elements you get -6m^4-m^3. Srry if this makes no sense
Answer:
To multiply rational expressions, first factor all numerators and denominators and cancel any factors you can. Then multiply what you have left.
Step-by-step explanation:
Answer:
factors of 7: 1, 7
factors of 10: 2, 5
1*-2 = -2
7*-5 = -35
...
-35 + -2 = -37
Step-by-step explanation:
The complete question in the attached figure
we know that
triangle OBR is a right triangle
so
<span>applying the Pythagorean theorem
</span>OB²=OR²+RB²----> OB²=3²+4²-----> 25
OB=√25-----> OB=5 units
the answer is OB=5 units
