Answer:

x = 7+√(3), 7-√(3)

Step-by-step explanation:

x^2 - 14x + ___ = -46 + ___

x^2 - 14x + 49 = -46 + 49

(x-7)^2 = 3

√(3) = x-7

x = 7+√(3), 7-√(3)

Please look at the picture;;<br> I thought it was Y=7x-48 and I’m not sure what to do

Answer:

  y = 7x -48

Step-by-step explanation:

Your answer is correct. You just need to write it in the box without the "y =".

__

The 2-point form of the equation for a line is ...

  y = (y2 -y1)/(x2 -1x)(x -x1) +y1

  y = (8 -(-6))/(8 -6)(x -6) +(-6)

  y = 14/2(x -6) -6

  y = 7x -42 -6

  y = 7x -48

You probably want your answer to look like ...

  y=\boxed{7x-48}

The area of a rectangle is 32a^3b^4 square units. The length is 4a^2b. Find the width. show your work
kaheart [24]

Answer:

The answer to your question is width = 8ab³

Step-by-step explanation:

Data

Area = 32a³b⁴ u²

length = 4a²b   u

Formula

Area of a rectangle = width x length

Solve for width

                           width = \frac{Area}{length}

Substitution

                          width = \frac{32a^{3}b^{4}}{4a^{2}b}

Simplify using rules of exponents, just remember that in a division we subtract the exponents and divide the coefficients normally.

                          width = 8 a²b³
