Answer:

16x² + 64x + 64

Step-by-step explanation:

Given

A = 16x²

Increasing the sides by 2, substitute x = x + 2 into A

A = 16(x + 2)² ← expand factor using FOIL

= 16(x² + 4x + 4 ) ← distribute

= 16x² + 64x + 64

A granite monument has a volume of 25,365.4 cm3. The density of granite is 2.7 g/cm3. Use this information to calculate the mass

Vaselesa [24]

Answer:

<h3>The answer is 68,486.58 g</h3>

Step-by-step explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of granite monument =

25,365.4 cm³

density = 2.7 g/cm³

The mass of the granite monument is

mass = 25,365.4 × 2.7

We have the final answer as

<h3>68,486.58 g</h3>

Hope this helps you

Find the area of the following ellipse. a = 4.5 m; b = 5.5 m

LenaWriter [7]

Answer:

Area of ellipse is ≈ 77.78 $m^{2}$

Step-by-step explanation:

Given the dimension of ellipse

a = 4.5 m

b = 5.5 m

Now, Area of ellipse = $\pi ab$

= $\frac{22}{7}\times 4.5\times 5.5$

= $\frac{5445}{70}$

= 77.78 $m^{2}$

Hence Area of ellipse will be 77.78 $m^{2}$
