Answer:
the second one
Step-by-step explanation:
Hello There!
The area of a triangle can be found using this formula
where a and b = bases and h = height
The trapezoid shown has the following dimensions
top base = 9cm
bottom base = 14 cm
height = 12 cm
slant height = 13 cm
using this information, we plug in the values into the formula
So 
the equation we created matches the 2nd equation therefore the second one is your answer
The diagram in the question is a cylinder.
;The volume of a cylinder is given by;
Volume = πr²h
;Where π=3.14
r⇒radius of the base of the cylinder and
h ⇒ height of the cylinder.
∴Volume = 3.14×5²×3
=235.5 ft³
To the nearest cubic = 236 ft³
You would use the distance formula
Hope this helped
Answer:
so x + 2x+10 + 3x is 6x+10 then set it to equal 142. x = 22 quick maths and then just set this to every side
so
shortest side:
22
medium:
54
longest: 66.
hope this helped, Mark branliest!
Answer:
a=25
Step-by-step explanation:
Solve by subtracting 3 from both sides.
a/5=5
Multiply both sides by 5.
a=25
