15 - 7xy^2 - (y^3 - y^2x - 15)

Distribute negative sign
15 - 7xy^2 + -1(y^3 - y2x - 15)
15 + -7xy^2 + -1y^3 + -1(-xy^2) + (-1)(-15)
15 + -7xy^2 + -y^3 + x^2 + 15

Combine like terms
15 + - 7xy^2 + -y^3 +xy^2 + 15
( -7xy^2 + xy^2) + (-y^3) + (15 + 15)
-6xy^2 + -y^3+ 30

= -6xy^2 + -y^3+ 30

The height of a ball dropped from the top of a 450-foot tall building can be described by the expression
BaLLatris [955]

Answer:

The answer is 386 feet.

Step-by-step explanation:

This equation simply asks to plug in a value that gives you the final value of the height. 450 is the initial height, and r (or l) is referred to as the amount of seconds after the item is dropped. 16 is the constant value of feet that the ball drops within one second.

Therefore, by substituting 4 for r (or l) and multiplying it by 16, you will receive 64 feet in 4 seconds. Finally, you need to subtract this from 450 feet, giving you a final answer of 386 feet.

4+7x=-24 how do you solve this algebraic expression
Lady_Fox [76]

Answer:

In order to solve this algebraic expression, you need to get the variable x by itself

Step 1: subtract 4 from each side

4-4+7x=-24-4 (4-4=0, those cancel out) (-24-4=-28)

7x=-28

Step 2: divide both sides by 7

7x/7=-28/7 (7x/7=x) -28/7=-4)

Your final answer would be x=-4

Hope this helps ;)

At which angle will the hexagon rotate onto itself?<br><br> 60°<br> 90°<br> 120°<br> 180°
arsen [322]

The <em><u>correct answers</u></em> are:

60°, 120°, and 180°.

Explanation:

A hexagon has six angles.  A full circle is 360°; since there are 6 angles in the hexagon, it will rotate onto itself every 360/6 = 60°.  This means that the hexagon will rotate onto itself at angles that are multiples of 60°; this means that 120° and 180° will also do this.
