There are two coefficients, one for x raised to the first degree, and the other for x raised to the zeroth degree (i.e. constant term).

Thus:
coefficient for the constant term : 42   (i.e. 42x^0=42).
coefficient for the linear term: 2  (i.e. 2x^1=2x)

Answer:

The coefficient in the given expression is, 2

Step-by-step explanation:

Coefficient states that it is a multiplicative factor in some terms of a polynomial, series, or expression.

Given the expression: 42 + 2c

Here, c represents the variable.

To find the coefficient in the expression.

42 is the constant term.

2 is the coefficient of the variable c in the given expression.

Therefore, the coefficient in the given expression is, 2

Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard.

Answer:

Step-by-step explanation:

Find the complete question

Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard. She found the change of scale below.

Which is Zelie’s error?

Zelie should have divided both numbers by 14.

Zelie should have written the ratio as 28/7.

Zelie should have written the ratio as 14/8.

Zelie should have subtracted 14 from both numbers.

Original length of pool = 28ft

If he found that it need to be 14ft longer then the actual measure = 14th

given equation is;

(28 - 7)/14 - 7 = 14/7

Scale constant  = original length/actual length

Scale constant = 28/14

Scale constant = 2

Hence the scale constant is 2

According to the option, Zelei should have divided both numbers by 14.
