Create an equation with one solution of x = −4.

Answer:

What is missing is -5x - 20

Step-by-step explanation:

To find this, simply solve for the parenthesis as if it were a variable of its own. This will allow you to see exactly what is missing.

8x - (x - 20) = 2x - (_______)

8x - x + 20 = 2x - (_______)

7x + 20 = 2x - (_______)

5x + 20 = - (_______)

-5x - 20 = (_______)

So the answer for the parenthesis is -5x - 20

A triangle has sides with lengths of 60 centimeters, 63 centimeters, and 87 centimeters. Is it a right triangle

lozanna [386]

We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:
$60^2+63^2 = 87^2$
$7569 = 7569$

This is, indeed correct, thus, this is a right triangle.

Doing monomials. How do you do this one?

butalik [34]

$(- \frac{5}{10} )( \frac{ x^{3} }{ x^{3}} } )( \frac{ y^{3} }{ y^{3} y^{4} } )( \frac{z^{4} }{ z^{4} } )$ => $(- \frac{1}{2} )( \frac{1}{ y^{4} } ) => \frac{-1}{2 y^{4} } .$

Which is the side length of a cube with a volume of 2744 cm3? Please help

Elis [28]

$\sf~V=a^3$

Plug in what we know:

$\sf2744=a^3$

Find the cube root of both sides:

$\sf~a=\sqrt[3]{2744}$

Simplify:

$\sf~a=\boxed{\sf14}$
