How do I do this problem??
KiRa [710]
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! :)

If the side of a rectangular prism is doubled, how would this affect the area? How about the volume?
professor190 [17]

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

Find the volume on the following prims it says please help me!! I need to find the volume :)
Delvig [45]

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
