Is known that

(a + b)² = a² + 2.a.b + b²

So:

(x + 4)² = x² + 2.x.4 + 4² = x² + 8x + 16

Answer: x^2 +8x +16
Explanation:
each term in the second bracket must be multiplied by each term in the first bracket
⇒(x +4)^2=(x+4)(x+4)⇒(x+4(x+4)
=x(x+4)+4(x+4)
=(x×x)+(x×4)+ (4×x)+(4×4)
=x2+4x+4x+16
=x^2+8x+16


That's all

Complete the set of ordered pairs for the relation.
neonofarm [45]

The set of ordered pairs is:

{(-2, 2), (-1, 0), (0, 2), (1, 4), (2, 6)}

<h3>How to complete the set of ordered pairs?</h3>

Here we have the relation:

y = 2*|x + 1|

And the domain is x ∈ { -2, -1, 0, 1, 2}

Evaluating in the values of the domain, we get:

if x = -2.

y = 2*|-2 + 1| = 2

Then we have the ordered pair (-2, 2)

if x = -1

y = 2*|-1 + 1| = 0

Then we have the ordered pair (-1, 0)

if x = 0

y = 2*|0 + 1| = 2

Then we have the ordered pair (0, 2)

if x = 1

y = 2*|1 + 1| = 4

Then we have the ordered pair (1, 4)

if x = 2

y = 2*|2 + 1| = 6

Then we have the ordered pair (2, 6)

The set of ordered pairs is:

{(-2, 2), (-1, 0), (0, 2), (1, 4), (2, 6)}

josh bought followers for nancy. he spent a total of $14.85 and bought 13 flowers. if he knows lilies cost $1.25 and tulips cost
Serjik [45]

Answer:

x = lillies

y = tulips

x + y = 13

1.25x + .90y = 14.85

-1.25x - 1.25y = -16.25

1.25x + .90y = 14.85

-0.35y = -1.40

y = 4 tulips

x + 4 = 13

x = 9 lillies

(9 lillies, 4 tulips)
