For example, multiple both the numerator and denominator of 9/7 by 2.
This will give you a fraction of 18/14, which is equivalent.

You can do this with any number you like to create three equivalent fractions.

CAN SOMEONE MULTIPLY THIS PLEASE, ITS URGENT

____ [38]

Let's factorise it :

$\: {\qquad \dashrightarrow \sf ( {x}^{3} - 5)(x + 3) }$

$\: {\qquad \dashrightarrow \sf {x}^{3} (x + 3) + [-5(x + 3)] }$

Using Distributive property we get :

$\: {\qquad \dashrightarrow \sf {x}^{3} + {3x}^{3} + ( - 5x - 15) }$

$\: {\qquad \dashrightarrow \sf {x}^{3} + {3x}^{3} - 5x - 15 }$

$\: {\qquad \dashrightarrow \sf 4{x}^{3} - 5x - 15 }$

⠀

Therefore,

$\: {\qquad \dashrightarrow \sf ( {x}^{3} - 5)(x + 3) =4{x}^{3} - 5x - 15}$

Which expression is equivalent to 2^4 ⋅ 2^−7?

yaroslaw [1]

Remember
$(x^m)(x^n)=x^{m+n}$
and
$x^{-m}=\frac{1}{x^m}$

so
$(2^4)(2^{-7})=$
$2^{4-7}=$
$2^{-3}=$
$\frac{1}{2^3}=$
$\frac{1}{8}$

Find the equation of the line that is perpendicular to 3x + 2y = -2 and goes through the point (6,2)

notka56 [123]

Perpendicular lines have slopes that are inverse reciprocals of each other. That would give you the new slope in your equation. After that plug (6,2) into point slope form and solve to get your final equation.
