Use the Distance Formula to find the distance to the nearest tenth between A(-7, -4) and B(-2, 0).

1 answer:

8 0

A(-7,-4) B(-2,0)
√[(x'-x)^2+(y'-y)^2]
√(-2-(-7)^2+(0-(-4)^2
√(5^2)+(4^2)
√25+16
√41

the distance is approximately 6.4 units

Answer please answer please

Maru [420]

Step-by-step explanation:

angle EAB = 2x too, due to the laws of the same and mirrored angles when a line crosses 2 parallel lines.

the angle ABE is 180 - 6x, due to the fact that all angles around a single point on one side of a line ad up to 180 degrees.

similarly, the angle AEB is 180 - 4x.

and then we know the sum of all angles in a triangle is airways 180 degrees.

so,

180 = 2x + 180 - 4x + 180 - 6x

0 = 180 - 8x

8x = 180

x = 22.5

In the following exercises, multiply the binomials. Use any method. 266. (3rs − 7)(3rs − 4)

Novay_Z [31]

Answer:

Hence the expression $(3rs-7)(3rs-4)=9r^2s^2-33rs+28$

Step-by-step explanation:

Explanation

The given expression is (3rs-7)(3rs-4).
We have to multiply the given expression.
Multiply the (3rs-7) by -4, multiply the (3rs-7) by 3rs then add like terms.

$\begin{matrix}{} & {} & {} & {} & 3rs & - & 7 \\ \times & {} & {} & {} & 3rs & - & 4 \\ \end{matrix}$

_________________

$\begin{matrix}{} & {} & {} & - & 12rs & + & 28 \\ {} & {} & 9{{r}^2}{{s}^2} & - & 21rs & {} & {} \\ \end{matrix}$

________________

$\begin{matrix}{} & {} & 9{{r}^2}{{s}^2} & - & 33rs & + & 28 \\ \end{matrix}$
