D.

2,744 cm²

Answers

the answer is C.1,176 cm² it is a cube it has 6 sides so 6 time the side wich is 14 so 6*14 cm^2=1,176 cm^2

Does the expression 2b + 5b have like terms?

Answers

Answer:

Yes. 'b' is a like term

Step-by-step explanation:

The two terms have the same variable, B. This allows us to add them together directly. 2B + 5B = 7B

The curve produced by the water coming from a hose is sketched onto a graph with zeros at 1 and 5. The point (4,1) also lies on the curve. If h(x) represents the vertical distance from where the water first comes out of the hose and
x represents the horizontal distance, which statements are true? Check all that apply
The scenario can be represented by the function h(x)=-0256)(x-5).
The scenario can be represented by the function h(x)= 16)(x + 5).
The vertex is on the line x=25.
The greatest height that the water reaches is 15 units.
The scenario can be represented by the function h(x)=-166-5).

Answers

Answer:

A and C.

Step-by-step explanation:

From the problem, we deduct that the function has to be quadratic, because it's mention two zeros, which is proper of a polynomial expression with grade 2.

So, we can say that:

$h(x)=a(x-0)(x-5)$

Because, 5 and 0 are roots of the expression.

Also, we know that the point $(4,1)$ is on the curve, this means:

$h(4)=1$

Replacing this relation in the first expression, we have:

$1=a(4-5)$

$1=a(-1)\na=-1$

So, the expression would be:

$h(x)=-1(x-0)(x-5)$

$h(x)=-x(x-5)$

$h(x)=-x^(2) +5x$

If we graph, we could get the vertex easier.

You can see in the image, that the vertex is at x = 2.5

Therefore, the option C is the answer.

However, the first option has this function:

h(x) = –0.25(x)(x – 5).

Which also can be solution, because, if we try x = 4:

h(4) = –0.25(4)(4 – 5)=1

Therefore, option A is also part of the answer.

Answer

answer A and C are right

What is the solution to the equation?2 - Z/3 = 12

Please help me. Thanks~! ^^

A. z = -42

B. z = -34

C. z = 30

D. z = 42

Answers

The answer is C because you; need to add instead of subtracting to get a positive number.

2 - z / 3 = 12

Multiply both sides by 3 :

3 * 2 - 3 * ( z / 3 ) = 3 * 12

Refine :

6 - z = 36

Subtract 6 from both sides:

6 - z - 6 = 36 - 6

- z = 30

Divide both sides by - 1

- z / - 1 = 30 / - 1

z = - 30

answer C

hope this helps!
