Answer:
The area of the composite area is 400 square millimeters.
Step-by-step explanation:
The area of the composite figure (
), in square millimeters, is found by multiplying the area of the equivalent rectangle, in which a semicircle of the original rectangle is move to the opposite side of the figure, so that quantity of area is conserved:
(1)
Where:
- Width, in millimeters.
- Height, in millimeters.
If we know that 
, the area of the composite figure is:
The area of the composite area is 400 square millimeters.
Answer:
10x^3+14x^2-25x-35
Step-by-step explanation:
f(x) = 2x^2 -5
g(x)= 5x+7
f(g(x)) = (2x^2 -5)(5x+7)
5x(2x^2 -5)+7(2x^2 -5)
10x^3-25x+14x^2-35
10x^3+14x^2-25x-35
Answer:
Mariya is 1 year old
Vikram is 7 years old
Step-by-step explanation:
Here, we want to know the present ages of Mariya and Vikram.
Let the present age of Mariya be M and the present age of Vikram be V
From the question, we are told that in 6 years time, Mariya will be as old as Vikram is now
Thus, mathematically;
M + 6 = V ••••••(i)
Furthermore , in 2 years time Vikram will be 3 time older than Mariya
Mathematically;
( V + 2) = 3( M + 2)
V + 2 = 3M + 6
V = 3M + 6-2
V = 3M + 4 •••••••(ii)
So let’s equate the V
3m + 4 = m + 6
3m -m = 6-4
2m = 2
m = 1
But V = m + 6
V = 1 + 6
V = 7
Answer:
regular polygon:
E & C
irregular polygon:
A & B
Not polygon:
D & F
Explanation:
<em>regular</em><em> polygon</em><em>:</em><em> </em>
has equal sides however the number of side and regular shape and it has equal angles between its sides. <em>"</em><em>ex"</em><em> </em><em>(</em><em>equilateral</em><em> </em><em>triangle</em><em>)</em>
as in figure C & E.
<em>Irregular</em><em> </em><em>polygon</em><em>:</em>
the opposite of regular polygon but both has a straight line all over the shape. as in figure B & A.
not a polygon:
it's may be a circle or a part of it.as in figure D & F.
