use the identity below to complete the tasks a^3-b^3=(a-b)(a^2+ab+b^2) when using the identity for the difference of two cubes t

zheka24 [161]

Answer:

see explanation

Step-by-step explanation:

Given that the the difference of cubes is

a³ - b³ = (a - b)(a² + ab + b²)

Given

64 $x^{6}$ - 27 ← a difference of cubes

with a = 4x² and b = 3, thus

= (4x²)³ - 3³

= (4x² - 3)(16 $x^{4}$ + 12x² + 9) ← in factored form

Can someone please help me ASAP

Sonja [21]

Answer:

x^2 + 5n = 4mx

=> x^2 - 4mx + 5n = 0

D=0 (since one root then roots are equal)

b^2-4ac = 0

(-4m)^2 - 4(1)(5n) = 0

16m^2 - 20n = 0

16m^2 = 20n

8m^2 = 10n

4m^2 = 5n

hope it helps.......

. Dillion deposits $150 into his account. One week later, he withdraws $26. Write an addition expression to represent this situa

Lina20 [59]

Answer:

$Expression = x + 150 +(- 26)$

$124 higher

Step-by-step explanation:

Given

$Deposit = \$150$

$Withdrawal = \$26$

Required

Represent the situation

Determine how much higher or lower is the remaining amount

Let the initial amount in his account be represented with x

When he deposited, the balance becomes

$Balance = x + 150$

When he withdrew, the balance becomes

$Balance = x + 150 + (-26)$

Hence, the algebraic expression is

$Expression = x + 150 +(- 26)$

Calculating how much higher or lower

$Balance = x + 150 + (-26)$

Open bracket

$Balance = x + 150 -26$

$Balance = x + 124$

Recall that the initial amount in the account is x

The difference between the balance and the x is as follows

$Difference = x + 124 - x$

$Difference = \$124$

<em>Hence, the account has a higher of $124 after both transactions</em>
