Answer:
x=2
Step-by-step explanation:
let the number be x
9x-8=6+2x
9x-2x=6+8
7x=14
x=14/7
x=2
Answer:
area of shaded: 30 m²
Explanation:
- Here triangle is inscribed in a rectangle.
- Rectangle area: Length * Width
- Triangle area: (1/2) * base * height
- The triangle here is shaded.
Steps:
Rectangle area: 6 * 10 = 60 m²
Triangle area: (1/2) * 6 * 10 = 30 m² .......this is the area of shaded.
Answer:
D
Step-by-step explanation:
Here , we are given with a circle on cartesian plane , and we need to find the <em>equation of the circle </em>, We are also given that it's centre is at <em>(5,-6) </em>{ From graph } and it's radius is<em> 3 units</em> . Now , as we know, the standard equation of a circle is where <em>(h,k) </em>is the centre of the circle and radius is <em>r</em> . Now , our equation will be ;
<em>This is the required equation of Circle </em>
Or if you want to proceed it further , then you will get <em>x² + y² - 10x + 12y + 50 = 0 </em>
Answer:
76.5in²
Step-by-step explanation:
First we will find the area of the square. This is done by multiplying the side length (9in) by itself.
The area of the square is 81in².
Next we will find the area of the triangular hole. We can use the formula , where b is the base of the triangle (3) and h is the height of the triangle (3).
The area of the triangle is 4.5in².
Now we can find the area of the figure by subtracting the area of the square and the area of the triangular hole.
The area of the figure is 76.5in².
That is the answer
