For this case, we have that by definition, the area of a triangle is given by:

A = \frac {b * h} {2}

where:

b: It's the base

h: It's the height

In this case we have:

b = 21 \ ft\\h = 6 \ ft

Substituting:

A = \frac {21 * 6} {2}\\A = 63 \ ft ^ 2

Answer:

63 \ ft ^ 2

gulaghasi [49]

Each tweet would cost between 1 and 140 pennies you can write that as an inequality [1 ≤ x ≤ 140] Since you can't tweet 0 characters or above 140.

if you want to change it to pounds divide by 100.

A) 1 ≤ x ≤ 140

B) Each character costs a penny, you can't tweet less than 1 character or above 140.

What is the equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3 ​
andreyandreev [35.5K]

<u>Answer:</u>

The equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3 ​is y+6=\frac{1}{3}(x+2)

<u>Solution:</u>

Given that line passes through (-2, -6) and has slope of 1/3

We have to find the equation of the line

The point slope form is given as

y-b=m(x-a)

where m is the slope of the line and a, b are the x, y coordinates of the given point through which the line passes.

Here in this question, m = 1/3 and a = -2 and b = -6

By substituting in point slope form we get,

y - (-6) = \frac{1}{3}(x - (-2))\\\\y + 6 = \frac{1}{3}(x + 2)

Hence the equation of a line, in point slope form that passes through (-2, -6) and has a slope of 1/3 ​is y+6=\frac{1}{3}(x+2)

What is the simplest form of this expression?<br> 4(y + 2) - 2
Semenov [28]
The simplest form is 4y+6?


you distribute the 4 to everything in the parentheses and then combine like terms so you would combine the 8 and -2
