Choose SSS, SAS, or AA to prove
the triangles are similar.

A. SSS
B. SAS
C. AA

Choose SSS, SAS, or AA to prove the triangles are similar.

A. SSS

B. SAS

C. AA

As, all sides are given so we can use SSS to prove the triangles are similar.

So, correct option is A.

As, all three sides are given so let's check ratio of all three sides.

1.

2.

3.

As, all sides are in equal ratio.

So, by SSS

∆1 ~ ∆2

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

1/3 + 1/5 = 8/15.

step-by-step explanation:
