What did i do wrong?
irakobra [83]

Answer:

27x +42+ 3x²

Step-by-step explanation:

so im learning this rn in class and what you do is FOIL

So its stands for

First

Outside

Inside

Last

(3x+6)(x+7)

(3x+6)(x+7) -- 3x² (if you have x times x it is x to the second power)

(3x+6)(x+7) -- 21x

(3x+6)(x+7) -- 6x

(3x+6)(x+7) -- 42

Now add 21x and 6x

27x +42+ 3x²

you must have added the 21 and 6 incorrectly.

Please help thank you.

Hello!

Let O be the center of the sphere, A the tangency point and B the location of the satellite.

m<ABO = 1/2m(b) = 1/2 * 138 = 69

m<OAB = 90

m<AOB = 180 - 90 - 69 = 21

21 * 2 = 42

The answer is 42°

Hope this helps!

What is the percent of change from 50 to 23?
Taya2010 [7]

Answer:

50 is the old value and 23 is the new value. In this case we have a negative change (decrease) of -54 percent because the new value is smaller than the old value. Using this tool you can find the percent decrease for any value.
