The area of a square is found by squaring one of its sides, (A = s2). A certain square has an area of z2 + 18z + 81. Factor the trinomial to find a side of the square.a. side = z + 27
b. side = z + 18
c. side = z + 9

Answers

Answer 1

Answer: A = s²
A = z² + 18 z + 81
z² + 18 z + 81 = z² + 9 z + 9 z + 81 = z ( z + 9 ) + 9 ( z + 9 ) =
= ( z + 9 ) ( z + 9 ) = ( z + 9 )²
Answer:
C ) side = z + 9

Answer 2

Answer:

Answer:

option c is correct.

side = z+9

Step-by-step explanation:

Area of a square(A) is given by:

$A = s^2$

where,

s is the side of the square.

As per the statement:

A certain square has an area of $z^2 + 18z + 81.$

⇒ $A = z^2 + 18z + 81$

Substitute in [1] we have;

$z^2 + 18z + 81 = s^2$

Taking square root both sides we have;

$√(z^2 + 18z + 81) =s$

Using identity rule:

$(a+b)^2 =a^2+2ab+b^2$

then;

$√(z^2 + 2(1)(9)z + 9^2) =s$

⇒ $√((z+9)^2) =s$

Simplify:

$z+9 = s$

s = z+9

Therefore, a side of the square. is, z+9

For what value of θ, in degrees, is sin θ = cos 58°?

Answers

Answer:

The value of $\theta$ is, 32 degree.

Step-by-step explanation:

Given the equation:

$\sin \theta = \cos 58^(\circ)$

We have to find the value of $\theta$

Using the rule:

$\cos (90-\theta) = \sin \theta$

then;

$\cos (90-\theta) = \cos 58^(\circ)$

Comparing both sides we have;

$90^(\circ)-\theta = 58^(\circ)$

Subtract 90 from both sides we have;

$-\theta = -32^(\circ)$

Simplify:

$\theta = 32^(\circ)$

Therefore, the value of $\theta$ is, 32 degree.

What is the area of the polygon given below? Please explain how you got the answer

Answers

The area is the sum of 3 rectangles areas
First          12 * 19 = 228
Second       3 * 3   = 9
Third           2 * 17 = 34

so the area = 228 + 34 + 9 = 271 square units

The total area is 271 square units.
