Step-by-step explanation:
9x - 2 = 4x + 8 → (9-4)x = 8 + 2 → 5x = 10 → x = 10/2 = 5

Answer:
C. 336 cm²
Step-by-step explanation:
Area formulas:
Area of a right triangle: a × b ÷ 2
Area of rectangle: length × width
-----------------------------------------------------------------------------------------------------------------
In this figure, there is a rectangle with a width of 12 and a height of 6.
; the area of the rectangle is 72 cm².
There are two right triangles with legs of 6 and 8.
There are two right triangles so..
The area of a single triangle is 24 cm²; the area of the triangles combined is 48 cm.
There is a rectangle in the middle with a width of 8 and a height of 12.
The area of the rectangle is 96 cm².
Lastly, there is a rectangle with a width of 10 and a height of 12.
The area of the rectangle is 120 cm².
Now, add the areas of every shape to find your answer.
Step-by-step explanation:
Answer:
18 edges
Step-by-step explanation:
v-e+f=2
number of vertices(12) - number of edges (18) + number of faces(8) = 2
Answer:
745.5
Step-by-step explanation:
To answer this question we need to find the perimeter and multiply it by three. To do that we can start by adding 85 yards plus 85 yards for both sides of the rectangle which equals 170. Then we need to add the circumference of the semicircles. To do that we can use the formula C = 2(3.14)r. for that we need to find the radius which is the diameter divided by 2 which is 12.5. Then we can plug that into the formula to get C=(2)(3.14)(12.5). After solving that we get 78.5 which we can add to 170 to get the perimeter which is 248.5 . However we are NOT done since jasmine is running 3 laps we need to multiply 248.5 by 3 to get an answer of 745.5.
10!
There's two halves in a whole. So we could do 5 x 2 to get our answer. Hope this helps!
