Answer:
they are like terms
Step-by-step explanation:
the sign ± is not a matter only veriable and power
In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.
It is 120 because you have to divide 210 by 7 which is 30 then multiply by 4 so 30 x 4 = 120.
Answer:
( 2×8) - [ ( 5 + 15 ) ÷ 5] = 32
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Given equation = 2x18-5+15/5=32
First we multiply first two letters,
then ( 2 × 18) = 36
Now, we add 5 and 15 then divide it by 5,
So, ( 5 + 15 ) ÷ 5 = 20 ÷ 5 = 4
Now we subtract 4 from 36,
Then 36 - 4 = 32
Hence the correct parentheses = ( 2×8) - [ ( 5 + 15 ) ÷ 5] = 32
Answer:
y-2=9(x+3)
Step-by-step explanation:
y-y1=m(x-x1)
y-2=9(x-(-3))
y-2=9(x+3)
Angles are formed by intersection of non-collinear lines, rays and planes.
<u>Part A</u>
<u>1. Contradictory Example</u>
A contradictory example to the given definition is that:
When the rays are collinear; the rays do not form an angle, but they form a line
<u>2. A more accurate definition</u>
A more accurate definition is that:
An angle is formed at the intersection of two non-collinear rays that have the same endpoint
<u>Part B</u>
<u>Example of an undefined term</u>
Undefined terms do not have a formal definition; an example is the plane.
A plane pertains to angles because it determines the parameter to be measured.
