Answer: 18 cm^2
Step-by-step explanation:
There are four equal triangle and a rectangle.
Formula of a rectangle = b * h = 2*3 = 6
Formula of triangle = but there four of them so we times them by 4, this leaves us with 2 (b * h) = 2(2*3) = 12
Area of pentagon = area of all triangles + rectangle
Area of pentagon = 12 + 6 = 18
Hope this helps.
Answer:
(1,4)
Step-by-step explanation:
y=x+3
y=4x
Substitute the second equation into the first equation
4x = x+3
Subtract x from each side
4x-x = x-x+3
3x =3
Divide each side by 3
3x/3 =3/3
x =1
Now we need to find y
y =4x
y = 4*1
y=4
Answer:
2x² + 3x + 8 + 7/x-4
Step-by-step explanation:
For this problem, we can use synthetic division.
4 | 2 -5 -4 -25
| 8 12 32
|_________
2 3 8 7/x-4
This means the quotient is 2x² + 3x + 8 + 7/x-4.
Answer:
Step-by-step explanation:
The picture of the question in the attached figure
step 1
Let
r ---> the radius of the sector
s ---> the arc length of sector
Find the radius r
we know that
solve for r
step 2
Find the value of s
substitute the value of r
step 3
we know that
The area of complete circle is equal to
The complete circle subtends a central angle of 2π radians
so
using proportion find the area of the sector by a central angle of angle theta
Let
A ---> the area of sector with central angle theta
substitute the value of r
