Answer:

400/81 cm²

Step-by-step explanation:

FE : DC

1 : 3

Since area ABCD = 400

s² = 400

s = 20

FE = ⅓(20) = 20/3 cm

IH : FE

1 : 3

IH = ⅓(20/3) = 20/9 cm

Area of HIJK:

(20/9)² = 400/81 cm²

Find the area of the shaded region. Round your answer to the nearest tenth. PLZ HELP

Ksju [112]

Answer:

30.96 m²

Step-by-step explanation:

In white there are four parts of a circle, so we can split the 12 m in half to show the radius, and then solve to find the area of the full circle.

A = r²

a = (6)²

a = (36)

a = 113.04

Then you find the area of the whole box.

12 x 12 = 144

Then you subtract the area of the circle in white from the area of the whole box.

144 - 113.04 = 30.96 m²

So that’s the area of the shaded region.

Use long division to find the quotient Q(x) and the remainder R(x) when P(x) is divided by d(x) and express P(x) in the for

lilavasa [31]

Answer:

$P(x)=(x+9)(x^2-7x+52)+3$

Step-by-step explanation:

We are given that

$P(x)=x^3+2x^2-11x+471$

$d(x)=x+9$

We have to find the value of Q(x) and Remainder R(x).

Quotient, $Q(x)=x^2-7x+52$

Remainder, $R(x)=3$

We know that

$Dividend=Divisor\times Quotient+Remainder$

$P(x)=(x+9)(x^2-7x+52)+3$
