Answer:
A right triangle
Step-by-step explanation:
plot the points and then connect them with line segments.
The answer would be (-5x-3)(-5x+3)
Palelogram area:
Knowing the base and the height, the area of the parallelogram is calculated by its formula:
A1 = b * h
Where
b: base
h: height.
We have then
b = root ((- 4 - (- 10)) ^ 2+ (2-2) ^ 2) = 6
h = root ((- 7 - (- 7)) ^ 2+ (3-2) ^ 2) = 1
A1 = (6) * (1) = 6 units ^ 2
Rectangle area
A2 = L * W
Where
L: long
W: Wide
We have then:
L = root ((1 - (- 2)) ^ 2 + (- 3 - (- 4)) ^ 2) = 3.16227766
W = root ((- 4 - (- 2)) ^ 2+ (2 - (- 4)) ^ 2) = 6.32455532
A2 = (3.16227766) * (6.32455532)
A2 = 20 units ^ 2
The total area is the sum of both ares:
A = A1 + A2
A = 6 + 20
A = 26 units ^ 2
Answer:
the area of this figure
A = 26 units ^ 2
Find use the distributive property and bring down the ending result (21)
-3x-6=21
Next, add 6 on both sides and you should get:
-3x = 27
The last step is, you divide -3 from 27 and you end up with 9. So, the total answer is x = 9
5x=2x=35
7x=35
x=35/7
x=5
5x=25 girls
2x=10 boys
hope i helped you
