It should be 4x-(2x-5)=7.
Answer:
l = p - 2w / 2
Step-by-step explanation:
You can make your own problem and plug it in. I substituted 5 for w and 6 for l. That means the perimeter would be 22. Now plug those numbers into all the problems. The one that gives you the correct answer is the top right answer.
6 = 22 - 5 / 2
Multiply 7 by 4 by 5 and the answer will be 140

Answer:
7236.86
Step-by-step explanation:
the formula for volume of a sphere is V = 4/3pi(r^3).
(volume equals 4 over 3 times pi times radius to the power of 3)
we know that the radius is 12mm. 12^3 = 1728mm. Now we'll multiply 4/3 by pi.
4/3 x pi = 4.188.
now multiply 4.188 by 1728 and you get 7236.86.
Tell me if this is the right answer.
According to PEMDAS, you should do the parenthesis first, then the multiplication, then the subtraction. Let's do it:
75-(8+45/3)*7
= 75-(8+15)*7
= 75- 23*7
= 75- 161
= -86.
Hope this helps~
