Let
w--------> <span>width of the border

we know that
(11-2w)*(13-2w)=80--------> 11*13-22w-26w+4w</span>²=80
143-48w+4w²-80=0
4w²-48w +63=0

using a graph tool------> to resolve the second order equation
see the attached figure

the solution are
w1=1.5
w2-10.5--------> is not solution

the answer is
the width of the border is w=1.5 in

Where would (0.5,2) be potted ? Please answer this !!
NISA [10]

 (0.5,2)

0.5 is x value

2 is y value

         l

         l

---------------

        l

        l

x value is on dashed line (0.5)

y value is on more separated line going up and down. (2)

To plot 0.5, you can put it as an equation. 0.5= 1/2. So to plot it, 0.5 is half of 1. So plot it as in between the 1 and 0.

To plot 2 go up to the two on the y axis and then go over 0.5 and plot a point.

That is you're plotted point for (0.5,2)


Hope it helps!

A:

In triangle ABC, angles A and B have the same measure, while angle C is 42 degrees larger than each of the other two angles. Find the measure of angle Step-by-step explanation:

Find the measures of angles A, B, and C in triangle ABC, if measure of angle B = 5 times the measure of angle A measure of angle C = measure of angle A + 110

✓ A + B + C = 180 A + 5A + A+110 = 180

C. "David's equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings"

they are technically saying "Look we have 12,350 to use. How long (y) will the savings (12,350) last after using 240 each month (x)
so the amount they use *PER* month gets subtracted from the savings because they are using that money to pay with

Hope this helps :)
