Check that 2b+b and 3b have the same value when b is 1,2, and 3. Do 2b+b and 3b have the same value for all values of b? Explain

Inessa [10]

Answer:

Expression 2b+b and 3b have same values for all values of b.

Step-by-step explanation:

Given the two expression $2b+b$ and $3b$ and values of b as 1, 2 and 3.

Consider first expression that is, $2b+b$ .

Substituting the value of $b=1$ ,

$2\left(1\right)+\left(1\right)=2+1=3$ ....1

Substituting the value of $b=2$ ,

$2\left(2\right)+\left(2\right)=4+2=6$ ....2

Substituting the value of $b=3$ ,

$2\left(3\right)+\left(3\right)=6+3=9$ ....3

Consider second expression that is, $3b$ .

Substituting the value of $b=1$ ,

$3\left(1\right)=3$ ....4

Substituting the value of $b=2$ ,

$3\left(2\right)=6$ ....5

Substituting the value of $b=3$ ,

$3\left(3\right)=9$ ....6

For value of b=1, equation 1 and equation 4 are same, for value of b=2, equation 2 and equation 5 are same and for value of b=3 equation 3 and equation 6 are same.

Therefore both expression are same for all values of b.

A fish tank, shaped as a cube, has a volume of 36 liters, or 2,197 in cubed. What are the dimensions of the fish tank in Inches?

lutik1710 [3]

Answer:

l x w x h = 2,197

If l=w=h then it is a perfect cube.

The cube root of 2,197 is 13

Therefore, the cube is 13 x 13 x 13 inches.

Help me please ASAP

Mashutka [201]

Answer: $\frac{5}{35}$

Step-by-step explanation:

Since, the total number of contestant = 7,

Thus, the probability that out of 3 contestant, me and my friend is chosen

= $\frac{2_C_2\times 5_C_1}{7_C_3}$

= $\frac{\frac{2!}{2!0!}\times \frac{5!}{1!\times 4!}}{\frac{7!}{4!\times 3!}}$

= $\frac{1\times 5}{\frac{7\times 6\times 5\times 4!}{4!\times 6}}$

= $\frac{5}{35}$

⇒ Third Option is correct.
