Answer:

Well perimeter is adding up all the sides since it's a rectangle the first one is just 6 + 6 + 4 + 4 = 20 cm

The second would be 9 + 9 + 12 + 12 = 42 cm if this is not an option or if it is wrong let me know and I will try again

Write the equation of the line shown (3,6) (3,-4)
lozanna [386]

Answer:

The equation of line is given as  x=3

Step-by-step explanation:

Point on the line given :

(3,6),(3,-4)

We can find the slope of the line first from the given points.

Slope(m)=\frac{y_2-y_1}{x_2-x_1} = \frac{-4-6}{3-3}=\frac{-10}{0}== Undefined.

The slope of the line is undefined which means that the line is parallel to y-axis.

From the points known to us we can tell that the line passes through x=3

∴ The equation of line is given as  x=3

Rachel works at a bookstore. On Tuesday, she sold twice as many books as she did on Monday. On Wednesday, she sold 6 fewer books
natali 33 [55]
Let m = the amount books Rachel sold on Monday.
then t = the amount books Rachel sold on Tuesday.<span>
then w = </span><span>the amount books Rachel sold on Wednesday.

On Tuesday she sold twice as she did on Monday.
 t = m * 2

On Wednesday she sold 6 fewer books than she did on Tuesday
w = t - 6

Now for the fun.

t = m * 2
w = t - 6

Substitute t for real value

w = m * 2 - 6

Now solve for m.

w - 6 = m * 2 <-- Transpose the 6
(w-6)/2 = m <-- Transpose the 2.
m = (w-2)/2 < The Law of Reflexive Property of Equality</span>

Solve the equation v+5/-9 - 4 = -6/8
tamaranim1 [39]
First you simplify both sides of the equation to make v+-41/9=-3/4.

Then add -41/9 to both sides to get the answer which is 137/36

v=137/36
