Answer:

Part A: (4x+3) (4x+3)

Part B: 4 (x+y) (x-y)

(If this is not the answer you are looking for, sorry)

Step-by-step explanation:

Part A: (16x²+24x+9)

FOIL

(4x + 3) (4x +3) = 16x²+24x+9

(4x) (4x) = 16x²

(4x) (3) = 12x

(4x) (3) = 12x

12x + 12x = 24x

(3) (3) = 9

Part B: (4x²-4y²)

4 (x² - y²)

You have to factor it completely

4 (x + y) (x - y)

(Make sure to use FOIL to double check)

If θ  = 2 pi then S = 2 pi R       the circumference of the circle

θ = S / R = 9.7 / 9 = 1.08 rad

Since 1 rad = 360 / (2 pi) = 57.3 deg

Let me know if you found this helpful! It means a lot!

Answer:

2148.9 m^3

Explanation:

The formula for the volume of a sphere is V=πr^2h

We know that r, the radius, is 6 metres.
We also know that h, the height is 19 metres.

If we substitute those values into the formula, we get 2148.85 m^3.

And 2148.85 to the nearest tenth is 2148.9 m^3.

Answers

The scale factor when a triangle of 8cm side is enlarged to a triangle of 64cm side is 8.

Side of the first triangle = 8cm

Side of the second triangle = 64cm

What is a scale factor?

A scale factor is a number by which the size or dimension of an object is enlarged or diminished.

For example, if an equilateral triangle with a side x is dilated by a scale factor of 2, the enlarged size of the side will be 2a.

So, scale factor = side of the second triangle/ corresponding side of the first triangle.

Scale factor = 64/8

Scale factor = 8

Therefore, The scale factor when a triangle of 8cm side is enlarged to a triangle of 64cm side is 8.

How to represent mathematical expression?

Expression are numbers, symbols and operators grouped together that show the value of something.

Dion bought 3 pounds of oranges and 2 pounds of grapefruit.

The expression to represents the amount of money Dion spent on fruit is as follows:

let

x = cost of each pounds of oranges

y = cost of each pounds of grapefruit

Therefore,

total cost = 3x + 2y

Let's evaluate the expression

total cost = 3(0.99) + 2(1.59)

total cost = 2.97 + 3.18

total cost = 6.15 dollars

What is the value of `x` in the solution of the system of equations?`3x-2y=6``\ \ x+2y=10`

Answer:

x = 4

Step-by-step explanation:

3x - 2y = 6 → (1)

x + 2y = 10 → (2)

add (1 ) and (2) term by term to eliminate y

(3x + x) + (- 2y + 2y) = 6 + 10 , that is

4x = 16 ( divide both sides by 4 )

The shopkeeper giving 80% discount on the Christmas tree during the sale.

What is discount?

A discount is an amount that is subtracted from the regular price of an item.

What is discount percent formula?

[tex]discount \ percent = \frac{original \ price - final \ price }{original \ price } \times 100[/tex]

According to the given question.

The marked price of the Christmas tree i.e. original price = $364.

The price of the Christmas tree on sale i.e. final price  = $72.80

So,

The discount given on the Christmas tree

= Original price - final price

= $364 - $72.80

= 291.2

Therefore,

Discount percent  = [tex]\frac{291.2}{364} (100)= 80 \ percent[/tex]

Hence, the shopkeeper giving 80% discount on the Christmas tree during the sale.
