5(4x + 2) ÷ 7y From the expression above, provide an example of each of the following: sum, term, product, factor, quotient, and
2 answers:
Answer:
Given Expression :
We have to give example of Sum , Term , Product , Factor , Quotient and Coefficient
Sum : addition of 4x & 2 .i.e., 4x + 2
Term: Term can be a single number , variable, or the product of both.
for Ex- 7y , 20x , 10
Product: Multiplication of 5 & (4x+2) , Multiplication of 4 & x
and Multiplication of 7 & y
Factor: factor is a part of product.
factor of term 7y = 7 & y
factor of term 20y = 5 , 2, 2 & y
factor of term 10 = 5 & 2
Quotient:
Coefficient: Coefficient of a term is a number which is in product with variable. for ex,
Coefficient of 7y = 7
Coefficient of 20x = 20
Coefficient of 10 = 10

Answer:
(6, 9 ) and r = 3
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + y² - 12x - 18y + 108 = 0
Rearrange the x- terms and the y- terms together and subtract 108 from both sides, that is
x² - 12x + y² - 18y = - 108
To obtain standard form use the method of completing the square
add ( half the coefficient of the x and y terms )² to both sides
x² + 2(- 6)x + 36 + y² + 2(- 9)y + 81 = - 108 + 36 + 81
(x - 6)² + (y - 9)² = 9 ← in standard form
with centre = (6, 9 ) and r = = 3
