Answer 1
Answer:

Answer:

X:-5, 2

Step-by-step explanation:

If you factor the expression, it becomes (x+5)(x-2). In order to make each expression in the paranthesis equal to 0, x must be -5 or 2.

h has to be a number so that when you divide it by nine it will equal nine.
Reversing this, it would look like this.
9*9=h
h=81
To get rid of the denominator and get h by itself, multiply each side by 9:

(h)/(9) = h
9 * 9 = 81

h = 81

h will equal 81.

All rectangles are parallelograms. Are all parallelograms rectangles? Explain

Answers

The statement that all parallelograms are rectangles is false

How to determine the true statement?

The statement is given as:

All rectangles are parallelograms

The properties of rectangles are

  • Opposite sides are equal
  • Opposite sides are parallel
  • Adjacent sides are perpendicular

The properties of parallelogram are

  • Opposite sides are equal
  • Opposite sides are parallel

Using the above properties, we can conclude that the statement that all parallelograms are rectangles is false

Select the explicit formula for the sequence that correspond to this geometric series: 6 + 18 + 54 + 162 + 486 ak = 6 • 3k – 1
ak = 3 • 6k – 1
ak = 6 • 3k
ak = 3 • 6k

Answers

The  explicit formula for the sequence that correspond to this geometric series: 6 + 18 + 54 + 162 + 486 is a_(k)=6.(3)^k^-^1

What is Sequence?

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

The given geometric series is 6 + 18 + 54 + 162 + 486

a is the first term which is 6

Let us find the common ratio r which is 18/6 =3

The general form of geometric sequence is aa_(k)=a.(r)^k^-^1

Let us plug in the values of a and r in the above formula

a_(k)=6.(3)^k^-^1

Hence, the  explicit formula for the sequence that correspond to this geometric series: 6 + 18 + 54 + 162 + 486 is a_(k)=6.(3)^k^-^1
