(6x+3) (4x-5) (simp) I try to do this one and got the answer 24x^2-18x-15 but I was told it was wrong

Gemiola [76]

Answer:

(6x+3) (4x-5) = 24x^2 -30x +12x -15 = 24x^2 -18x -15

I get the same answer. I guess we're both wrong?

Or do they want it reduced to:

8x^2 -6x -5

If x3 = 27, what is the value of x?

ipn [44]

Answer:

The value of x is 3

Step-by-step explanation:

Given:

$x^3 = 27$

To Find:

x = ?

Solution:

We Know that

$a = (a^3)^\frac{1}{3}$

$a = (a)^\frac{3}{3}$

We can write 27 as $3 \times 3 \times 3$ = $3^3$

Taking cube root on both sides

$(x^3)^{\frac{1}{3} }= (3^3)^{\frac{1}{3}}$

$x^{\frac{3}{3}} = 3^{\frac{3}{3}}$

$x^1 = 3^1$

x = 3
