Mila [183]3 years ago

Answer:

-24.5 or 7i or -71 (see below)

Step-by-step explanation:

Im gonna guess that you mean (22-16)(2x+49)=0

Therefore, since one of the brackets must be equal to 0 and 22-16 is 6, 2x+49=0 so x is -24.5

However, if you meant (22-16)(x^2+49)=0

then x^2+49=0 so x^2 =-49

Therefore, the answer is complex and therefore 7i or -7i

WITCHER [35]
The heart pumps 750*24/9=2000 gallons, and the kidney pumps 100*24/6=400 gallons. This is a difference of 2000-400=1600 gallons.

Wanda is working on her predictions for the next few days. She calculates that there is a 20% chance of rain on Monday and a 20%
Mariana [72]

Answer:

36%

Step-by-step explanation:

the <em>complement </em>of it raining on at least one of these days = it not raining on any day

this means that if it does not rain on at least one day, it does not rain on any day

thus,

1 - probability of it not raining at all = probability it rains at least one day

probability it doesn't rain on monday = 1- 20% = 80%

probability it doesn't rain on tuesday = 1 - 20% = 80%

probability it doesn't rain on monday AND it doesn't rain on tuesday = probability it doesn't rain at all

P(A and B) = P(A) * P(B) = 0.8 * 0.8 = 0.64

1 - 0.64 = 0.36 as our answer

Which is the simplified rational expression for r2-4r+5/r-4
Sliva [168]

Step-by-step explanation:

\frac{ {r}^{2}  - 4r + 5}{r - 4}  -  \frac{ {r}^{2}  + 2r - 8}{r - 4}  \\  =  \frac{ ({r}^{2} - 4r + 5) - ( {r}^{2}  + 2r - 8) }{r + 4}  \\  =   \frac{ {r}^{2} -  {r}^{2}  - 4r - 2r + 5 - 8 }{r - 4}  \\  =   \frac{ - 6r - 3}{r - 4}
