What is (3/4 x - 1/2 y) + ( - 7/4 x - 5/2 y) in standard form

Step-by-step explanation:

The LCD here is 4.  Rewrite the entire expression using that denominator:

3x - 2y - 7x - 10

            4

Combining like terms, we get:

 -4x - 2y - 10

           4

This can be reduced to  -x - (1/2)y - (10/4).  This has the form Ax + By + C.

Normally, if this were an equation, we'd write Ax + By + C = 0, or, in this particular case,

-x - (1/2)y - (10/4) = 0  or

x + (1/2)y + 10/4 = 0

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
