I can help u but just give me 5 mins or 2 to help u :) ill get back to u right away
U can use real world numbers and problems to help
First find the difference of the numerator. to do this multiply 1/x by 2 and 1/2 by x. you should get (2-x)/2x. now moving on to the whole fraction. then multiply the (2-x)/2x by 2x and the (x-2) by 2x. you should get (2-x)/(2x)(x-2). now factor out a negative from the (x-2) at the denominator to get -(2-x). so now you can cancel the (2-x) from the numerator and denominator! the answer will be 1/-2x! :)
Answer:
Step-by-step explanation:
The area will be increased by 4 times and volume will be increased by 8 times
Area of rectangular prism = 2 (lb+bh +hl)
When sides are doubled, Area = 2 (2l * 2b +2b *2h + 2h*2l)
= 4 * 2 (lb+bh +hl)
Volume of rectangular prism = lbh
When sides are doubled, Volume = 2l * 2h * 2b = 8 lbh
Answer:
V = 277.088 m³
Step-by-step explanation:
Volume of Cylinder Formula: V = πr²h
We are given <em>r</em> = 4.2 and <em>h</em> = 5, so simply plug it into the formula and solve:
V = π(4.2)²(5)
V = 17.64π(5)
V = 88.2π
V = 277.088
