Is there a picture where are the angles?
Let,
The number be "x"
According to the question,
x² + 5x = 176
x² + 5x - 176 = 0
x² + 16x - 11x - 176 = 0
x (x + 16) - 11 ( x + 16) = 0
(x + 16) (x - 11) = 0
Now,
Using zero product property:
Either,
x + 16 = 0
x = -16
Or,
x - 11 = 0
x = 11
So,
The number is either "-16" or "11".
Cross-Multiply
7/2=3/n
7*n=(3)*(2)
7n=6
Divide both sides by 7
7n/7=6/7
n=6/7 or n= 0.85
I hope that's help again !
Given the coordinates of two points, P1 and P2, the distance formula between these two points is deduced.
d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
To find the area of the figure we must first find the area of the rectangle and add the area of the parallelogram.
rectangle area
A = (L) * (w)
L = root ((- 6-2) ^ 2 + (- 1-1) ^ 2) = 8.25
w = root ((- 6 - (- 5)) ^ 2 + (- 1 - (- 5)) ^ 2) = 4.12
A = (8.25) * (4.12) = 33.99
Parallelogram area
A = (b) * (h)
b = root ((3-3) ^ 2 + (3 - (- 3)) ^ 2) = 6
h = root ((3-2) ^ 2 + (3-3) ^ 2) = 1
A = (6) * (1) = 6
The total area is then
Atotal = 33.99 + 6 = 39.99 units ^ 2
Answer
the area of this figure is 39.99 units ^ 2
Surface = flat area, it doesn't have a height, just an area.
