A rectangle has a height of w2 + 3w + 9 and a width of w2 + 2.

Express the area of the entire rectangle.

Your answer should be a polynomial in standard form.
22

The area = w^4 + 3w^3 + 11w^2 + 6w + 18.

Step-by-step explanation:

Area = height * width

=  (w^2 + 2)(w^2 + 3w + 9)

We multiply the second bracket by w^2,  then by  +2:

= w^2(w^2 + 3w + 9) + 2(w^2 + 3w + 9)

=  w^4 + 3w^3 + 9w^2 + 2w^2 + 6w + 18

=  w^4 + 3w^3 + 11w^2 + 6w + 18.

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

From the information given,

Height = w² + 3w + 9

Width = w² + 2

The expression for the area would be

Area = (w² + 3w + 9)(w² + 2)

We would expand the brackets by multiplying each term in the first bracket by each term in the second bracket. It becomes

Area = w⁴ + 2w² + 3w³ + 6w + 9w² + 18

Collecting like terms, it becomes

Area = w⁴ + 3w³ + 2w² + 9w² + 6w + 18

Area = w⁴ + 3w³ + 11w² + 6w + 18

the solution is h=10 because you add 9 to each side of the equation.

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
