Answer:
576 cubic ft
Step-by-step explanation:
Volume of prism is = area of base of prism * height
given prism is rectangular with length of 8 feet and width of 6 ft
area of rectangle is = length * width
for the given prism area of base = 8 * 6 = 48 square ft
height of prism = 12ft
therefore volume of prism = area of base of prism * height
= 48 square ft *12 ft = 576 cubic ft
What question??? I just see an "o".
4x2 * (x2 + 5x - 3) is the final factorization
Answer:
again i didnt answer the question i just found someone who did
hope it helps :)
Step-by-step explanation:
Let +a+ = liters of pure acid needed
Let +b+ = liters of 10% solution needed
+.1b+ = liters of pure acid in 10% solution
-----------------------------------------
(1) +a+%2B+b+=+135+
(2) +%28+a+%2B.1b+%29+%2F+135+=+.2+
---------------------------
(2) +a+%2B+.1b+=+27+
(2) +10a+%2B+b+=+270+
------------------------
Subtract (1) from (2)
(2) +10a+%2B+b+=+270+
(1) +-a+-+b+=+-135+
----------------------
+9a+=+135+
+a+=+15+
and
(1) +a+%2B+b+=+135+
(1) +15+%2B+b+=+135+
(1) +b+=+120+
-------------------
15 liters of pure acid are needed
120 liters of 10% solution are needed
--------------
check:
(2) +%28+a+%2B.1b+%29+%2F+135+=+.2+
(2) +%28+15+%2B.1%2A120+%29+%2F+135+=+.2+
(2) +27%2F135+=+.2+
(2) +27+=+27+
Answer:
-12
Step-by-step explanation:
1. 3(-4)²+3(-4)
48 - 12
= 36
2. 2(-4)+5
= -8+5 = -3
3. 36/-3
= -12
