Answer:
a
Step-by-step explanation:
the answer is a. 6 faces 12 edges and 8 vertices
<span>When solving a system of equations by substitution, meant by a useless result of (12=12) is no solution. The answer is letter B, the equation has no solution because it can have infinite solution. I hope the answer helps, thank you for posting your question here. </span>
rounded part is a semicircle so the area for that is the area of a circle ÷ 2
so
area of the rectangle + (area of the circle ÷ 2) = answer
24 * 14 = 336 = area of the rectangle
14 ÷ 2 = r
(pi * 7^2) ÷ 2
(pi * 49) ÷ 2 = 153.86 ÷ 2 = 76.93 = area of semicircle
336 + 76.93 = 412.93 ft^2 = answer
-10 = -10 + 7m
Add 10 to each side: 0 = 7m
Divide each side by 7 : 0 = m
Please take a second and just LOOK at the equation you started with.
It says:
-- You have this number '-10' .
-- Your number -10 is going to be exactly the same size
after you add 7 of something to it.
The ONLY way that could happen is if the 'something' is 'nothing' .
' m ' must be nothing.
Multiply to remove the variable from the denominator.
