Calculate the area of triangle abc with altitude cd, given a(-3,-4) b(-6,2) c(0,0) d(-4,-2)
14 square units
15 square units
18 square units
20 square units

answer:   second option is correct.

step-by-step explanation:

since we have given that

a(-3,-4) b(-6,2) c(0,0) d(-4,-2)

and we have altitude cd with base ab.

length of ab is given by

length of cd is given by

area of triangle abc is given by

hence, second option is correct.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
