Flura [38]3 years ago
4 0

Answer:

The factorization of the given expression is (c - 7)(c+7).

Step-by-step explanation:

Consider the provided information.

c^2-49

Use the formula of the difference of the square in order to factorize the given expression: a^2-b^2=(a+b)(a-b)

c^2-49=c^2 - 7^2

c^2-49=(c - 7)(c+7)

Hence, the factorization of the given expression is (c - 7)(c+7).

Write an equation for the line in the given form.
nexus9112 [7]

Answer:

  5x +y = 34

Step-by-step explanation:

Since a point and slope are given, it is convenient to start with point-slope form, then rearrange the equation to put it into standard form.

For slope m through point (h, k), the point-slope form of the equation of a line is usually written ...

  y -k = m(x -h)

For m=-5 and (h, k) = (6, 4), the equation is ...

  y -4 = -5(x -6)

  y -4 = -5x +30 . . . . . eliminate parentheses

__

Standard form looks like ...

  ax + by = c

where a > 0 and GCD(a, b, c) = 1. Here's how we can get there.

  5x +y -4 = 30 . . . . . . add 5x

  5x +y = 34 . . . . . . . . . add 4 to get standard form.

Art [367]

Answer:

Perimeter = 1 unit

Step-by-step explanation:

length \ is \ a \ fraction \ 2  \ over \ 3 = \frac{2}{3}\\\\Width \ is \ a \ fraction \ 1 \ over \ 3 = \frac{1}{3}\\\\Perimeter = 2 ( l + w)\\

               = 2 \times (\frac{2}{3} + \frac{1}{3}) \\\\=2 \times (\frac{3}{3})\\\\= 1 unit
