I’m not 100% sure but I think it’s D.
<h3><u>
Answer:</u></h3>
<h3><u>
Step-by-step explanation:</u></h3>
- x2 + 2x + 1 + y2 + 2x + 3
- => 2x + 2x + 1 + 2y + 2x + 3
- => 4x + 1 + 2y + 2x + 3
- => 6x + 1 + 2y + 3
- => <u>6x + 4 + 2y</u>
<h3><u>
Conclusion:</u></h3>
Therefore, the above answer is correct.
Hoped this helped.

Answer:
- (A)Six of the one-half cubes would have a volume of 3 cubic units.
- (D)Three of the one-third cubes will make 1 unit cube.
- (E)Two of the one-half cubes will make 1 unit cube.
- (F)Both stacks will have a volume of 3 cubic units.
Step-by-step explanation:
Marissa claims that stacking 6 blocks with dimensions of
will give the same volume as stacking 9 blocks with dimensions of
.
First, let us examine the volume of each of the blocks.
<u>For Block 1</u>
The dimensions are:

Volume of 1 block = 
Volume of 6 blocks of dimension

<u>For Block 2
</u>
The dimensions are:
Volume of 1 block =
Volume of 9 blocks of dimension
The following statements out of Marissa's claim are true:
(A)Six of the one-half cubes would have a volume of 3 cubic units.
(D)Three of the one-third cubes will make 1 unit cube.

(E)Two of the one-half cubes will make 1 unit cube.

(F)Both stacks will have a volume of 3 cubic units.
