Answer:
324 cubic inches
Step-by-step explanation:
The dimensions are now 18 x 18 x 1, since you are cutting an inch off each side.
324 cubic inches
9514 1404 393
Answer:
C) -1 +21i
Step-by-step explanation:
For many purposes, "i" can be treated as though it is a variable. Collect terms in the usual way.
(-2 +12i) -(-1 -9i) . . . . given
= -2 +12i +1 +9i . . . . use the distributive property to eliminate parentheses
= (-2+1) +(12i +9i) . . . group like terms
= -1 +21i
The question is asking for the cubic feet inside the prism, which means it wants the volume.
The volume equation is:
Volume= length x width x height
The issue is: the measurements of the prism are given to us in inches, while the problem asks for feet. We just need to convert each measurement, by dividing each by 12, since there are 12 inches per foot.
40 inches/12=3.33 feet
45 inches/12=3.75 feet
30 inches/12=2.5 feet
Now, we just have to plug in the numbers we found to solve for the volume.
V=(3.33 feet)(3.75 feet)(2.5 feet)
V=31.22 cubic feet
5+5= 10
10 time 9b is 90b
10 times -7 is -70
Then 90b-70
Answer:
-3
