Replace ∗ with a monomial so that the derived expression may be represented as a square of a binomial: * +14b+49
anyanavicka [17]

Answer:

  * = b²

Step-by-step explanation:

You know that the square of a binomial is of the form ...

  (x + y)² = x² + 2xy + y²

Matching given terms, we have ...

  49 = y²

  2xy = 14b

Solving the first of these relations for y, we have

  y = √49 = 7

Putting that in the second relation and solving for x, we find ...

  2x·7 = 14b

  14x = 14b

  x = b

Then the first term of the expansion, x², will be b².

The missing term is b².

Abigail and Spencer calculate the slope of the line between the points (3,-1) and (5,4) in different ways. Abigail calculates th
telo118 [61]

Answer:

Spencer and Abigail are correct

Lauren is incorrect

Step-by-step explanation:

Spencer and Abigail are correct

Slope = change in y ÷ change in x

Or  m=\dfrac{y_2-y_1}{x_2-x_1}

Let (x_1,y_1) = (3, -1)

Let (x_2,y_2) = (5, 4)

\implies m=\dfrac{4-(-1)}{5-3}=\dfrac52

This is Spencer's method

Let (x_1,y_1) = (5, 4)

Let (x_2,y_2) = (3, -1)

\implies m=\dfrac{-1-4}{3-5}=\dfrac52

This is Abigail's method

It doesn't matter which point you label as point 1 and point 2, as long as you carry out the slope calculation correctly.

Lauren's calculation is wrong as she calculated her slope as:

m=\dfrac{y_2-y_1}{x_1-x_2}

where it should have been m=\dfrac{y_2-y_1}{x_2-x_1}
