Answer: 6
Step-by-step explanation:
the area of the base is the triangle base
the area of a triangle is bh/2
that looks like a perpendicular sign in the top left so b = 3 and h = 4
so area = 3*4/2 = 6
Simple....
you have:
3x-9=7x+12
To even solve this....isolate the variable your are trying to solve for....
3x-9=7x+12
-3x -3x
-9=4x+12
-9=4x+12
-12 -12
-21=4x
Simplify.....


Thus, your answer.
Answer:
A D E
Step-by-step explanation:
A) The formula for the area of a triangle is 
D) The base is 8 and the height is 14 so the area of the triangle is 56 meters squared.
E) Volume is
meters cubed.
Have a nice day :)
Answer:
Step-by-step explanation:
2x + 4 = 6x - 10
Minus 2x on both sides
4 = 4x - 10
Add 10 on both sides
14 = 4x
Divide by 4 on both sides
14/4 = x
x = 14/4
Simplify fraction
x = 7/2 or x = 3 1/2
