Answer:
terms, 2x, 3y , x and 7,
like terms, 2x, 3y, x and 7
Coefficient. 2 is the coefficient of 2x and 3 is the coefficient of 2y 1 is the coefficient of x
Constant. 7
Step-by-step explanation:
Given:
Terms are the number of parts in the expression.
there are four terms 2x, 3y , x and 7,
Like terms are the part of the polynomials. 2x, 3y and x are like terms because they both have an x attached. 7 is like terms because they have nothing attached.
The number that are attached to variable is called Coefficient.
So In the term 2x the number 2 is a coefficient because it is attached to x similarly 3y the number 3 is a coefficient because it is attached to y
and in the term x the number 1 is a coefficient.
Constant are the numbers that are not attached to any variable and it is not change. Such as 7 is the constant term.
Answer:
\angle ACB=40^{\circ}, \angle ABC=63^{\circ}
Step-by-step explanation:
Finding x:
We know that , because it's a straight line. So,
.
We know that the sum of the angles of any triangle will be .
So, we have that .
Combining like terms on the left gives .
Subtracting from both sides gives
.
Dividing both sides by gives
.
Finding missing angle measures:
.
.
So, and
and we're done!
Note: . Coincidence? If not, try and prove it!
