80x+30
-30x-30
=50x
You subtract 30 from each side
Step-by-step explanation:
1st way: 5x
2nd way: 5.x
third way: 5(x)
2/5 divides by 4/1 = 1/10
X=1/10
The volume of the new squad would be the volume of the original square times 11^2 which is 121
Answer:
294.14cm^2
Explanation:
First find the area of the whole piece of paper:
32*14=448
Then find the area of the two semicircles, semicircle + semicircle = 1 circle:
Area of a circle= (radius squared)(pi):
(7^2)(3.14) = 153.86
Subtract the area of the two semicircles from the whole paper area:
448-153.86 = 294.14
I hope this isn’t too confusing :)
