Step-by-step explanation:
5^5=25
-9+25(2-1)
-9+25*1

Answer:
Expansion for there will be 9 terms.
(a+b) ^n =nco a^n b^o+ nc1 a^(n-1) b^1+nc2 a^(n-2) b^2+nc3 a(n-3) b^3+nc4 a^(n-4) b^4+...........................ncn a^o b^n.
5th term of (2x+y)^8 = ?
5th term is nC4 a^(n-4) b^4
a=2x, b=y, n=8
therefore 8C4 (2x)^(8-4) (y)^4
8!/((8-4)! 4!) (2x)^4 y^4
40320/576 (16 x^4 ) (y^4)
70 (16x^4)(y^4)
1120 X^4 Y^4
Step-by-step explanation:
5v^2 + 25 = 115
5v^2 = 115 - 25
5v^2 = 90
v^2 = 90/5
v^2 = 18...take the square root of both sides eliminating the ^2
v = (+-) sqrt 18
v = 4.24 or v = -4.24
Answer:
<h2><u>440 ft.²</u></h2>
Step-by-step explanation:
Surface area of the object = 2 (lw + wh + hl) = 2 (10× 6 + 6 × 10 + 10 × 10)
= 2 ( 60 + 60 + 100) = 2 × 220 = 440 ft.²
