As per the problem,

Marco wants to use the distributive property to find the value of 17 • 69 + 17 • 31.

We have been asked to find , which expression can be used?

As per the distributive property , we know that

a(b+c)=a.b+a.c

Now apply this on the given expression we get

17. 69 + 17 .31=17(69+31)

Hence the expression , which can be used is 17(69+31)

The scatter plot below shows the relationship between the length (x) in meters and mass f(x) in kg of a marine animal
Semmy [17]

Answer:

Option C.

Step-by-step explanation:

As we can see from the graph, we have plotted the different points.

If the line drawn through the scatter plots, shows the relationship between the length x and mass f(x) then the function will be in the form of

f(x) = mx + b

where m = slope of the line that fits the best

b = y-intercept of the line

Since the plotted line passes through two pints (1, 1) and (10, 94).

Then the slope m = \frac{y-y'}{x-x'}

m = \frac{(94-1)}{10-1}

m = \frac{93}{9}

m = 10.3

Now we place the coordinates (1, 1) in the equation to find the value of y-intercept b.

1 = 10.3 + b

b = 1 - 10.3

b = -9.3 ≈ 9

So the function will be f(x) = 10.3x - 9

Option C is the answer.

Find the value of n .<br> 6/n = 24/28<br> y = ___.
il63 [147K]

Answer:

n=7

Step-by-step explanation:

Cross multiply, isolate the variable, and divide by the coefficient to solve.

\frac{6}{n}=\frac{24}{28} \\ \\ 24n=168 \\ \\ n=7

Plug back in to check.

\frac{6}{7}=0.857142857 \\ \\ \frac{24}{28} =0.857142857

PLEASE HELP!!!
mafiozo [28]

The product of the given polynomials is 12x^{6}y+8x²y^{4}.

The given polynomial is 4x²y(3x⁴+2y³).

We need to find the product of the given polynomials.

<h3>How to multiply the polynomials?</h3>

To multiply two polynomials: multiply each term in one polynomial by each term in the other polynomial. add those answers together, and simplify if needed.

Now, using the distributive property we get 4x²y(3x⁴+2y³)=4x²y×3x⁴+4x²y×2y³

=12x^{6}y+8x²y^{4}

Therefore, the product of the given polynomials is 12x^{6}y+8x²y^{4}.

A polynomial of the 5th degree with a leading coefficient of 7 and a constant term of 6???
Fiesta28 [93]

Answer:

The last option: 7x^5+2x^2+6\\

Step-by-step explanation:

Recall that the degree of a polynomial is the power of its leading term (the term with highest number of unknown factors).

In this case, the polynomials that show their leading term with degree "5", are the second and last options in the list of answers (notice power = 5 for the leading term in x , that is:  x^5

The only one of those that has a constant term (term with no "x" in it (last term in both cases) is the last option: 7x^5+2x^2+6
