Answer:

The opposite of integer 4 units away from -6 is 10.

Step-by-step explanation:

We know that the opposite of the opposite of a number, say 2, is the number itself.

That is:

Opposite of 2 is -2.

Then the opposite of -2 is:

- (-2) = 2

Now consider a number line.

The number that is 4 units away from -6 is -10.

4 units away implies moving backwards 4 units from -6.

So, the number is -10.

The opposite of -10 will be:

- (-10) = 10

Thus, the opposite of integer 4 units away from -6 is 10.

№1. Given: r=8 ft, π≈3.14

C=2×π×r=2×3.14×8=50.24=50.2 ft

A=π×r²=3.14×64=200.96=201 ft²

Answer: 50.2 ft; 201 ft²

№2. Given: D=11 cm, π≈3.14

d=2r or r=2/d, so if d is 11 cm, then r is 11÷2=5.5 cm

C=2×π×r=πD=3.14×11=34.54=34.5 cm

A=π×r²=3.14×(5.5)²=94.985=95 cm²

Answer: 34.5 cm; 95 cm²

What is the factored form of _________?

enyata [817]

Answer:

Step-by-step explanation:

The expression given is a difference of cubes and factors as

a³ - b³ = (a - b)(a² + ab + b²)

8 $x^{24}$ = (2 $x^{8}$ )³ ⇒ a = 2 $x^{8}$

27 $y^{6}$ = (3y²)³ ⇒ b = 3y²

Hence 2 factors are

(2 $x^{8}$ - 3y²) and

((2 $x^{8}$ )² + (2 $x^{8}$ × 3y²) + (3y²)²)

= (4 $x^{16}$ + 6 $x^{8}$ y² + 9 $y^{4}$ )

Hence the factored form of the expression is C
