Answer:
x²+5x-49
Step-by-step explanation:
-7² -x+6x+x²
combine like terms
-x+6x is 5x
simplify -7² is -49
now rewrite the equation
x²+5x-49
B. 16
if the length of each side is 16in, the total length would be 32in.
(16 x 2 = 32)
because the length is equal to twice the width, divide 32 by 2
(32/2 = 16)
16 + 32 = 48
To determine the time it takes for the penny to reach the ground, we use the relation of height and time given above. We do as follows:

0 =−4.9t^2+(0)t+150
t = sqrt( 150/4.9)
t = 5.53 s
Hope this answers the question. Have a nice day.</span>
These 5 bottles with lemonade which contains 150 millilitres in each bottle so it would be 150 x 5 to find how many millilires there is in all
For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9
