Simplify 5(3x-6)-8(3x-7)<br><br> Can someone explain how to do this in English?
Lunna [17]
Remember the distributive property? It goes like x(a+b)=xa+xb... For example 3(6+7)=(3*6)+(3*7)=39
Same here
5(3x-6)-8(3x-7)
do the thing
(15x-30)-(24x-56)
Take parentheses off.
15x-30-24x+56
//WHY PLUS 56 NOT MINUS?
//because there was a minus sign outside the original parentheses, so the signs inside have to be flipped when the parentheses is taken off
//Let's simplify now
15x-24x-30+56
-9x+26

A stuntman jumping off a 20-m-High building is modeled by the equation h=20-5t^2, where t is the same in seconds. A high-speed c
Alchen [17]

Answer: 1\leq t\leq \sqrt{2}


Step-by-step explanation:

1. You know that the high-speed camera is ready to film him between 15 meters and 10 meters above the ground.

2. The problem gives you the following equation:

h=20-5t^{2}

3. Therefore, you must calculate the time when h=15 and when h=10, as following:

h=15\\15=20-5t^{2}\\5t^{2}=5\\t=\sqrt{1}\\t=1  


h=10\\10=20-5t^{2}\\5t^{2}=10\\t=\sqrt{2}

4. Therefore, the answer is:

1\leq t\leq \sqrt{2}
