6n+1 = 25
subtract 1 from each side
6n+1-1 = 25-1
6n = 24
divide each side by 6
6n/6 = 24/6
n =4
Answer: 45
Use PEMDAS
first do what in the parentheses
(8+7)
8 + 7 = 15
Now we have
3(15)
This is multiplication
3 x 15 = 45
1. find volume
V=LWH
V=25*13*14
V=4550
each covers 1000
how many will cover the whole thing?
we can't put 4 becuase that leaves 550 uncovered
add another
5 is answer (it is too much , but at leas not too little) answer is D
2.
V=LWH
V=6*4*10
V=240
answer is D
3. count how many are there, don't forget the hidden ones
13 cubes
volume=legnth tiems width times height
cubes so
v=side^3
side=3
3^3=27
13 cubes
13*27=351 in^3
challenge (this is meant to challenge you, not for you to ask people, but I will solve anyway, robbin you of experience)
V=LWH
V=5880
H=30
5880=LW30
divide both sides by 30
196=LW
they have square bases so L=W
196=L^2
sqrt both sides
14=L=W
the side legnth is 14in
Answer:
f(x)=(x-3)^2-7
Step-by-step explanation:
Vertex form: f(x) = a(x-h)^2+k
x^2-6x+9+2=f(x)+9
(x-3)^2+2=f(x)+9
f(x)=(x-3)^2-7
