δabc ~ δdef
δabc ~ δefd
δabc ~ δdfe
δabc ~ δfed

Answer : The name of similar triangles are,

Step-by-step explanation :

Condition of similar triangles:

If two corresponding angles are equal.

If three corresponding sides are in same ratio.

The ratio of two pairs of corresponding sides are equal and their included angle are equal.

As we are given:

In ΔCBA and ΔDEF,

∠D congruent to ∠C

∠E congruent to ∠B

In this two corresponding angles are equal. So, these triangles are similar.

The name of similar triangles are,

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
