Plug in the given values and you'll see its option 2.

x=0 , f(x)  = 0^2 + 1 = 1

x = 1 , f(x) = 1^2 + 1 = 2

x = 2, f(x) = 2^2 + 1 = 5

Marissa claims that stacking 6 blocks with dimensions of One-half times 1 times 1 will give the same volume as stacking 9 blocks
quester [9]

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 \frac{1}{2}X1X1  will give the same volume as stacking 9 blocks with dimensions of \frac{1}{3}X1X1  .

First, let us examine the volume of each of the blocks.

<u>For Block 1</u>

The dimensions are:   \frac{1}{2}X1X1

Volume of 1 block =  \frac{1}{2}X1X1= \frac{1}{2} $ cubic units

Volume of 6 blocks of dimension   =6* \frac{1}{2} =3$ cubic units

<u>For Block 2 </u>

The dimensions are:   \frac{1}{3}X1X1

Volume of 1 block =  \frac{1}{3}X1X1=\frac{1}{3} $ cubic units

Volume of 9 blocks of dimension =9*\frac{1}{3} =3$ cubic units  

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.

 3*\frac{1}{3} =1$ cubic units

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

 2*\frac{1}{2} =1$ cubic units

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

3x − x − 1 = 15<br> What is x
azamat

Answer: x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−x−1=15

3x+−x+−1=15

(3x+−x)+(−1)=15(Combine Like Terms)

2x+−1=15

2x−1=15

Step 2: Add 1 to both sides.

2x−1+1=15+1

2x=16

Step 3: Divide both sides by 2.

2x /2 = 16 /2

x=8
