Answer:
7x+12
Step-by-step explanation:
since its neg, it take out { and } it no use.
if its like that, you add it.
so the equation: 3x+4x
that is 7x
+12 is after
so you do 7x+12
you can't simp it. So that is the answer
100% SURE
Given:
Container in the shape of two rectangular prism.
To find:
The volume of the container.
Solution:
The clear image of the container is attached below.
<u>Larger rectangular prism:</u>
Volume = length × width × height
= 8 × 5 × 10
= 400
Volume of larger rectangular prism = 400 in³
<u>Smaller rectangular prism:</u>
Volume = length × width × height
= 4 × 4 × 5
= 80
Volume of smaller rectangular prism = 80 in³
Volume of container = Volume of larger prism + Volume of smaller prism
= 400 in³ + 80 in³
= 480 in³
The volume of the container is 480 in³.
Answer:
16
Step-by-step explanation:
A = 2; S = 4
3A + 2.5S =
= 3(2) + 2.5(4)
= 6 + 10
= 16
Q=3x² + 5x -2
r=2-x²
s = 2x + 5
So plug in the values of q, r, and s into your equation q - [r+s], so
3x² + 5x -2 - [2-x² + 2x + 5], do the part in the brackets first
3x² + 5x -2 - [ -x² +2x +7], make sure the minus in front of the brackets is distributed to all the components
3x² + 5x -2 + x² -2x -7, then add/sub similar variables
4x² + 3x - 9, which is your answer, the last one...
