1) The given expression 7x^4 + 5x^2 + x - 9 is a polynomial.

2) The given expression 7x^6 - 4x^3 + 1/x is a trinomial.

<u>Step-by-step explanation</u>:

1) 7x^4 + 5x^2 + x - 9

  • The number of terms in the above expression is 4.
  • An algebraic expression with more than 3 terms is known as polynomial.
  • <u>The degree is the power of the x term in a expression</u>
  • first term = 7x^4 has a degree of 4.
  • second term = 5x^2 has a degree of 2.
  • third term = x has a degree of 1.
  • fourth term = 9 is a constant term with no degree.

2) 7x^6 - 4x - 1/x

  • The number of terms in the above expression is 3.
  • An algebraic expression with 3 terms is known as trinomial.
  • first term = 7x^6 has a degree of 6.
  • second term = 4x has a degree of 1.
  • third term = 1/x has a degree of -1.

Clare estimates that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4
attashe74 [19]

Her error in terms of inches was 2 inches while her percent error was 4.166%

Step-by-step explanation:

Step 1; From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.

We convert the feet into inches because 12 inches are equal to a feet.

4 feet = 4 × 12 inches = 48 inches

4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches

Error in terms of inches = 50 inches - 48 inches = 2 inches.

Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.

% error = (difference in values / actual value) × 100

Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%.

x=-12

(Please vote me Brainliest if this helped!)

Step-by-step explanation:

-\left(x+5\right)=7

\mathrm{Divide\:both\:sides\:by\:}-1

\frac{-\left(x+5\right)}{-1}=\frac{7}{-1}

\mathrm{Simplify}

x+5=-7

\mathrm{Subtract\:}5\mathrm{\:from\:both\:sides}
