Answer:
a = 4.8
Step-by-step explanation:
9 - 4a + 12 = 6a - 27
21 - 4a = 6a - 27
48 - 4a = 6a
48 = 10a
a = 4.8
Answer:
AC = 20
Step-by-step explanation:
C is the midpoint of BD.
That means that BC = CD
BC = x + 4
CD = 3x - 10
x + 4 = 3x - 10 Subtract x from both sides
4 = 3x - x - 10 Combine
4 = 2x - 10 Add 10 to both sides
4 + 10 = 2x - 10 + 10 Combine
14 = 2x Divide by 2
14/2 = 2x/2 Combine
7 = x
AC = AB + BC
AC = 2x - 5 + x + 4
AC = 3x - 1
AC = 3*7 - 1
AC = 21 - 1
AC = 20
Answer:
<u><em>1440</em></u>
Step-by-step explanation:
first you add 12 and 8 to get 20 then using the formula lwh = v you multiply 20 by 12 by 6 to get <u><em>1,440</em></u>
Also can you give brainliest to all of your questions bc it really hard to get brainliest and it be really nice you can choose who i dont really care but just please do it it helps a lot
Answer:
882 cubic ft.
Step-by-step explanation:
10.5 x 10.5 = 110.25
110.25 x 8 = 882 ft
2m
I think it is because the down it is 8 m
so there is 6m it the top
so it should be
8-6=2
