Answer:
C and G
Step-by-step explanation:
(x^2+4)^2+32=12x^2+48 is written as
.
We can simplify the expression using the term a by replacing x^2 + 4 with a.

This factors into (a-4)(a-8). Solve by setting each factor equal to 0 and solve for a.
a-4 = 0 a=4
a-8=0 a=8
Answer:
D) They are complementary angles.
Step-by-step explanation:
67+23=90
(x +3y)(x + 4y) tell me if you want me to tell you how I found it.
Answer:
324 and 144
Step-by-step explanation:
We require
a₁, a₂, a₃, a₄
where a₂ and a₃ are the required geometric means
The n th term of a geometric sequence is
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 729 and a₄ = 64, thus
729(r³) = 64 ( divide both sides by 729 )
r³ =
( take the cube root of both sides )
r =
=
, then
a₂ = 729 ×
= 81 × 4 = 324
a₃ = 324 ×
= 36 × 4 = 144
Thus
729, 324, 144, 64
