Nezavi [6.7K]

Answer:

3(2 - y)(2 + y)(4 + y²)

Step-by-step explanation:

48 - 3y⁴

Take 3 common:

3(16 - y⁴)

16 is 4² and y⁴ is (y²)²

3(4² - (y²)²)

Using a² - b² = (a - b)(a + b)

3(4 - y²)(4 + y²)

Again, 4 = 2²

3(2² - y²)(4 + y²)

3(2 - y)(2 + y)(4 + y²)

borishaifa [10]

The area of the flag that Joe created is 216 cm²

Step-by-step explanation:

Joe created triangular shaped flag for his history project

The height of the flag was 16 cm
The base of the flag was 27 cm

∵ The flag is shaped a triangle

∵ Area of a triangle = $\frac{1}{2}$ × base × height

∵ The base of the flag = 27 cm

∵ The height of the flag = 16 cm

- Substitute these values in the rule of the area above

∴ The area of the flag = $\frac{1}{2}$ × 27 × 16

∴ The area of the flag = 216 cm²

The area of the flag that Joe created is 216 cm²

the next discount is $48.95235

for Q8 is

Step-by-step explanation:

you are a very nice person for helping your mom. good luck for this!

ok let's work on question 7 first.

$63.99 is the cost of a skateboard.

15% of 63.99 = 10% + 5%

10% of 63.99 = 6.399 (move the decimal one place to the left)

5% of 63.99 = 1/2 of 6.399

1/2 x 6.399 = 3.1995

6.399 + 3.1995 = 9.5985

ok, so that's 15% of 63.99

now we need to take away 9.5985 from 63.99

63.99 - 9.5985 = 54.3915

the discount price of the skateboard is $54.3915

a further 10% is $5.43915

so take off that from the discount,

54.3915 - 5.43915 = 48.95235

the final price is $48.95235

QUESTION 8

shop A = 6.95 x 40

6.95 x 40 = $278

shop B = 20% of 325

20/100 * 325 = 65

325 - 65 = 260

therefore, shop B is cheaper.

hope this helped, good luck!
