Answer:
p = 21.312
Step-by-step explanation:
Divide 2.4 on both sides.
p = 21.312
Hope this helped!
First you must have the quadratic equal to zero. In order to do this you must subtract 7 to both sides
x^2 + 20x + (100 - 7) = 7 - 7
x^2 + 20x + 93 = 0
Now you must find two numbers who's sum equals 20 and their multiplication equal 93
Are there any? NO!
This means that you have to use the formula:

In this case:
a = 1
b = 20
c = 93



^^^We must simplify √28
√28 = 2√7
so...

simplify further:

-10 + √7
or
-10 - √7
***plus/minus = ±

Answer:
its 13
Step-by-step explanation:
Its 13 A
Answer:
Okay buddy the answer is 63 because if you look at all the angles they are suppose to add up to 180 so with the line D and A the angles is 128 so the angle on the other side is 52 so 52 plus65 is 117 so then 180-117 is 63

Answer:
I think it's G
Step-by-step explanation:
Since a=8 root 3=8×3=24cm
Yh so I multiplied the 24cm by 12cm
12cm×24cm=288cm squared
and the square root of 288cm is 96 root 3 cm squared
