Answer with explanation:

  • Monomial  = Polynomial with one term.
  • Binomial   = Polynomial with two terms.
  • Trinomial   = Polynomial with  three terms.
  • Degree - highest power of variable
  • Leading coefficient - Coefficient of the variable or variables with highest power.

1)\ \  4x^5 + 2

Name = Binomial   (as it has two terms)

Degree= 5     (power of x)

Leading Coefficient = 4   (coefficient of x^5)

2)\ \  - 4x + 7x^3-11

Name = trinomial  (as it has 3 terms)

Degree = 3   (highest power of x)

Leading Coefficien= 7    ( coefficient of  x^3)

3)\ \  18x^5y^3z

Name= Monomial  (as it has 1 term)

Degree= 5+3+1= 9    [Addition of power of all variables]

Leading Coefficient = 18

Suppose the lengths of two sides of a right triangle are represented by 2x and 3 (x + 1), and the longest side is 17 units. Find
densk [106]

Answer:

x=4

Step-by-step explanation:

<u>Step 1</u>:-

given the lengths of two sides of a right angle are represented by 2x and 3(x+1) and longest side is 17 units.

AB = 2x and BC = 3(x+1) and longest side AC= 17

by using Pythagoras theorem

AC^2 = AB^2 + BC^2

<u>step 2:-</u>

The hypotenuse is longest side is AC = 17 units

(17)^2 = 4x^2 +9(X+1)^2

on simplification, we will use formula

(a + b)^2 = a^2 +2ab+b^2

289 = 4x^2 +9(x^2+2x+1)

13x^2 +18x-280 = 0

finding factors  70 X 52 = 3640

13x^2 +70x-52x-280 = 0

13x^2 -52x+ 70x-280 = 0

Taking common , we get

13x(x-4)+70(x-4)=0

x-4=0 and 13x+70=0

x=4 and 13x =-70

x=4 and x=\frac{-70}{13}

we can not choose negative value so x value is 4

Final answer:- x = 4

<u>verification:-</u>

<u></u>AC^2 = AB^2 + BC^2<u></u>

289 = 4(4)^2+9(4+1)^2

289 = 64 +9(25)

289=289

Answer:

x = 6

Step-by-step explanation:

Hello!

x + 22 is equal to the sum of 5x - 6 and 4.

<h3>Solve for x</h3>
  • 5x - 6 + 4 = x + 22
  • 5x - 2 = x + 22
  • 4x - 2 = 22
  • 4x = 24
  • x = 6

The value of x is 6.
