The area of a rectangle is 42 m2, and the length is

MrRissso [65]

Answer:

length = 14 m

width = 7 m

Step-by-step explanation:

l = length

w = width

l = 2w - 8

w(2w - 8) = 42

2w² - 8w - 42 = 0

you can factor out a 2 to work with smaller numbers:

w² - 4w - 21 = 0

(w - 7)(w + 3) = 0

w = 7

'w' cannot equal a negative so we discount it as an answer

find length:

l = 2(7) - 8

l = 14 - 8 or 6m

[khan academy] hello, please help me with this if youre able to, thanks uwu

Ostrovityanka [42]

Answer:

11 units

Step-by-step explanation:

To calculate CD use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = C(- 4, 6) and (x₂, y₂ ) = D(- 4, - 5)

CD = $\sqrt{(-4+4)^2+(-5-6)^2}$

= $\sqrt{0^2+(-11)^2}$

= $\sqrt{0+121}$ = $\sqrt{121}$ = 11

Answer:

E: L is perpendicular to a line with slope $-\frac{3}{2}$ .

Lines are perpendicular if the negative reciprocal of the slope is equal. For example, the reciprocal of $\frac{2}{3}$ is $\frac{3}{2}$ (remember, to get the reciprocal, simply switch the numerator and the denominator).

So, the negative reciprocal of $\frac{2}{3}$ is $-\frac{3}{2}$ . This represents the slope of a line that is perpendicular.
