Describe the error Sadie made, and explain how to find the correct answer.
ZanzabumX [31]

Answer:

The answer to your question is below

Step-by-step explanation:

Sadie should have left inside the root an exponent lower than the root and the power of "a" is higher than "2", the root is squared.

Right solution

\sqrt{54a^{7}b^{3}  }

54 = 3² 6

a⁷ = a⁶ a

b³ = b² b

                 = \sqrt{3^{2}6 a^{6} a b^{2} b }

                = 3a^{6/2} b^{2/2} \sqrt{6ab}

               = 3 a^{3} b \sqrt{6ab}

Choose the equation that satisfies the data in the table.<br> HELP!!!!
harina [27]

The equation of the line represented by the table in slope intercept form is; y = ²/₁₅x + 2

<h3>How to solve equation in slope intercept form?</h3>

The formula for equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

The y-intercept will occur when x = 0. Thus, from the table, it is clear hat the y-intercept will be c = 2.

Let us find the slope using the first two points;

m = (2 - 0)/(0 - (-15))

m = 2/15

Thus, the equation is;

y = ²/₁₅x + 2

what is 7 7/10 rounded to the nearest whole number?? PLeaseee help! please explain your answer so I can learn it! PLeasee help
faltersainse [42]
The answer is 8 since it’s 7 7/10 the nearest whole number is 8 because 5-9 mean you round up and 1-4 mean u round down.

For example if you were rounding 10 3/10 to the nearest whole number your answer would be 10.
