What they said ^ I was just about to answer, but there’s popped up first lol
Answer: 9
Step-by-step explanation:
The expression (5x + 4)^3 in expanded form is 125 x3 + 300
x2 + 240 x + 64. The expression will
have also a root of x = -4/5. This is the form of trinomial expansion and can
be solve by multiplying the the term 3
times.

Answer:
A
Step-by-step explanation:
Attached is a copy of the figure with some of the clutter removed. The congruent angles marked with a single arc, and the parallel lines are given.
The angles marked with a double arc are congruent because they are alternate interior angles where transversal XZ crosses parallel lines XW and YZ. Of course, side XZ is congruent to itself.
Hence we have two angles and a side not between them that are congruent. We can declare ∆XWZ ≅ ∆ZYX by the AAS postulate. (choice A)
8% of 20 is 1.6
This is because you take the percentage and divide it by 100 so that you have a decimal, then multiply that by twenty. So, 8% ÷ 100 = 0.08 then 0.08 × 20 = 1.6
Hope this helps!
