Graph: 5 o---------------o 8
Break down the figure into 2 parts. Then use volume formula and multiply.
V=lwh
V=3x3x2
V=18ft^2
V=lwh
V=2x2x3
V=12ft^2
Then simply add.
18
+12

Answer:
Step-by-step explanation:
2x²+8=80
2x²=80-8=72
x²=72/2=36
x=±√36
x=±6
so x=6 is one solution other is x=-6
Answer:
it looks like it intersects at line t.
Step-by-step explanation:
I mean, just look at the picture. where does plane W and plane J touch? its not line p because that line is intersecting plane W and plane B, its not line a because that's intersecting planes V and J, and then its not B because they obviously do intersect.
I hope this helps you out and have a wonderful day!
Ax + 3 = 7 - bx .....add bx to both sides
ax + bx + 3 = 7 ...subtract 3 from each side
ax + bx = 7 - 3
ax + bx = 4 ....factor out x
x(a + b) = 4 ...divide both sides by (a + b)
x = 4 / (a + b) <==
