One of the ways would be 1+7. Another is absolute value |1+ -(7)|. Or even |1+7| which is what the first absolute value would turn into since everything in it turns to positive.

1/6 + 3/8 <br> A. 4/6<br> B. 4/8 <br> C. 4/14<br> D. 13/24

Naddika [18.5K]

Here is you're answer:

In order to get you're answer you need to find the common denominator then add.

$\frac{1}{6} + \frac{3}{8}$
Find the common denominator:
$CD = 48$
$= \frac{26}{48}$
Simplify:
$\frac{26}{48} \div 2 = \frac{13}{24}$
$= \frac{13}{24}$

Therefore you're answer is option D "13/24."

Hope this helps!

In what line do planes A and QRV intersect?

BabaBlast [244]

Answer:

Plane A and QRV intersection line is QR.

Explanation:

The plane QRV contains the rectangle QRVN. This rectangle intersects the plane A in the line QR.

Plane A and QRV intersection line is QR.

If one knows a specific line in one plane (for example, two points in the plane), and this line intersects the other plane, then its point of intersection.

Thus, it is on the line of intersection for the two planes.

Length of a rectangular prism is increased by factor of 1.5. The width is doubled and height is tripled. What is the new volume?

Alenkasestr [34]

The new volume is Nine time the original volume

Step-by-step explanation:

Let the length be 'l'

Let the height be 'h'

Let the width be 'w'

Volume of a rectangular prism= l x w x h

New length = 1.5l

New width = 2w

New height= 3h

New volume= (1.5l) x (2w) x (3h)

= 9 (l x w x h)

New volume= 9 ( original volume)

The new volume is 9 time the original volume
