Evaluate.
3/8 -(-1/12)

Step-by-step explanation:

We know that ,

⇒

Take the L.C.M ( Least Common Multiple )

L.C.M of 8 and 12 = 24

⇒ { 24 ÷ 8 = 3 , ∴ 3 × 3 and 24 ÷ 12 = 2 ,∴ 1 × 2 }

Multiply the numbers

⇒

Add the numbers

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
