Answer:
b = 40 and -40
Step-by-step explanation:
General form of Perfect square trinomial is a 2 + 2 a b + b 2
Therefore from 16 x 2 − b x + 25 a 2 = √ 16 x 2 , b 2 = 25 , then a = ± 4 x , b = ± 5 take consideration a=4x and b=-5 (different sign), then − b x = 2 ( 4 x ) ( − 5 ) − b x = − 40 x b = 40
The perfect square is ( 4 x − 5 ) 2 = 16 x 2 − 40 x + 25 .
if we consider a=4x and b=5 (same sign), then − b x = 2 ( 4 x ) ( 5 ) − b x = 40 x b = − 40
The perfect square is ( 4 x + 5 ) 2 = 16 x 2 + 40 x + 25 .
The first solution ( 4 x − 5 ) 2 is the best solution after comparing the expression given. I hope this helps, xx .
Y+ 2+ 6(y+6)
= Y+ 2+ 6y+ 36 (distributive property)
= Y+ 6y+ (2+ 36) (combine like terms)
= Y+ 6y+ 38
The final answer is Y+ 6y+ 38~
Answer:
3
Step-by-step explanation:
cause i wrote it on paper tho
The dimensions of the paint tray are:
W = 10 in
L = 12 in
D = 5 cm (1in / 2.54 cm) = 1.97 in
The total volume of the paint tray is:
Vt = WLD
Vt = (10)(12)(1.97) = 236.22 in3
Converting the volume of the paint to in3
Vp = 1 gal (231 in3 / 1gal) = 231 in3
Getting the difference,
236.22 in3 - 231in3 = 5.22 in3
Since the volume of tray is greater than the volume of the paint, the answer is:
The paint will not fill the tray by 5.22 in3.
