To figure this out first make the 4 4/9 into a improper fraction making it 40/9 and then multiply 2/7 x 40/9 then make is a mixed fraction :) hope this helped.

Find the area of each shaded region each outer polygon is regular <br><br><br> See the picture

PSYCHO15rus [73]

Answer:

Area of the shaded region = 3.46 square units

Step-by-step explanation:

Measure of the interior angle of a regular polygon = $\frac{(n - 2)\times180}{n}$

From the picture attached,

Number of sides of the given polygon 'n' = 6

Interior angle (∠BAF) of the given polygon = $\frac{(6 - 2)\times 180}{6}$

= 120°

Measure of ∠BAC = $\frac{120}{4}$

= 30°

Now we apply sine rule in ΔAGB,

sin(30°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

= $\frac{BG}{AB}$

BG = AB[sin(30°)]

= $2\times \frac{1}{2}$

= 1

By applying cosine rule in ΔABG,

cos(30°) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

= $\frac{AG}{AB}$

AG = AB[cos(30°)]

= $2\times \frac{\sqrt{3} }{2}$

= $\sqrt{3}$

AC = 2(AG)

= 2√3

Area of ΔABC = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(AC)(BG)$

= $\frac{1}{2}(2\sqrt{3} )(1)$

= $\sqrt{3}$

Area of the shaded region = Area of ΔABC + Area of ΔFED

= 2(Area of ΔABC)

= 2√3

= 3.46 square units

Please help in this question with explanation. pls

Answer:

V = x³ - 3x² + 3x - 1

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( s is the measure of the side )

Here s = x - 1 , thus

V = (x - 1)³

= (x - 1)(x - 1)(x - 1) ← expand the second pair using FOIL

= (x - 1)(x² - 2x + 1) ← distribute

= x³ - 2x² + x - x² + 2x - 1 ← collect like terms

= x³ - 3x² + 3x - 1

Classify the expression 7x3 as a monomial, binomial, trinomial, or polynomial

saul85 [17]

Hey Savion24,

A monomial can be defined as a number (1,2,3,4), a variable (x,y,z), or the product of numbers and variables (4x).

A binomial is a polynomial with two terms.

A trinomial is a polynomial with three terms.

Now lets have a look at the expression 7x³.

The given expression is a monomial as it is the product of a number and variable.
