Subtract: (3m2 + 2n) – (m2 + 2n)

2 answers:

8 0

The negative in front of the second bracket means that it's times by -1 so each of their signs switches:
3m^2+2n-m^2-2n
Add like terms
2m^2
the 2n cancels out

NEED HELP ASAP WORTH LOTS OF POINTS

otez555 [7]

Answer: 2.6

Step-by-step explanation:

PQ = QR (because it’s a rhombus), so

9b - 5 = 3b - 0.8

b = 0.7

And RS = PQ (again because rhombus), so RS = 9b - 5 = 1.3. Since RT is twice RS, we have

RT = 2(1.3) = 2.6.

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:

$1\leq t\leq \sqrt{2}$
