Answer:
1. Kite,
2. Kite.
Step-by-step explanation:
1. The quadrilateral form will have 2 equal pairs of adjacent sides which is a kite.
2. Find the slope and length of the sides:-
slopes (9-6)/ 0-3) = -1
(6-1) / (3-0) = 5/3
(6-1) / (-3-0) = -5/3
(9-6)/(3) = 1
Lengths = sqrt(9 + 9) = sqrt18
sqrt(25 + 9) = sqrt34
sqrt (25 + 9) = sqrt34
sqrt (9 + 9) = sqrt18.
This is another kite.
400 * 2% = 8
A: 8 * 6 = $48
B: 400 + 48 = $448
y=-9x-4
Slope intercept form uses the formula, y=mx+b, where m is the slope and b is the y- intercept.

<u>formula: </u>
(a+b)^2
= a^2+2ab+b^2
Here, we have x^2 (as in a^2)
and -6x (as in 2ab), which, we're missing the b^2
(I'm not really sure how to describe this but bare with me)
-6/2 (-6 is from the -6x) = -3 (the b)
-3^2 = -3*-3 which is equal to 9 (positive 9)
Writing it out -
x^2-6x+9 = -5
- Addition of inequality -
Since we add 9 to the left side, we have to add 9 to the right side; which gives us:
x^2-6x+9=4
Next, lets put the x^2-6x+9 as in (a+b)^2:
(x-3)^2 = 4
<em>Then let's do the square root of equality (square rooting both sides) :</em>
<u>x-3 = 2</u>
<em>Finally lets add 3 to both sides</em>
<u>x = 5</u>
THE ANSWER IS <u><em>x=5</em></u>

Answer:
24179 square inches
Step-by-step explanation:
In ΔRST, r = 620 inches, s = 840 inches and t=230 inches. Find the area of ΔRST to the nearest square inch.
We use the formula
Heron's formula = √s(s - a)(s - b)(s - c)
Where s = a + b + c/2
Solving for s
s = 620 + 840 + 230/2
s = 845
Solving for the area of the triangle
= √845 × (845 - 620) × (845 - 840) × (845 - 230)
= √584634375
= 24,179.213696893 square inches
Approximately = 24179 square inches
