Answer: h = 19, c = 132

Step-by-step explanation:

Oooh! This is a toughie!

Okay, first of all, there's a straight line on top. A straight line is 180 degrees.

This means we have to subtract 48 from 180.

180 - 48 = 132.

This means both a and b are 132.

F is equal to 151.

180 - 151 = e

e = 29

d = 29

g = 29

132 + 29 = 161

180 - 161 = 19

h = 19

19 + 29 = 48

180 - 48 = 132

c = 132

The cost of a swim club membership for a year is $170. The price consists of 12 monthly payments of $20 and a $20 registration fee. From equation, the mth payment is $12.5 per month.

Finding the value m of each monthly payment can be done using the equation 12m+20=170.

To find the amount(m), solve the equation 12m+20=170.

12m=150

M = 150/12

M= $12.5

As per the reference document attached thereby along with the question statement, (∠SOX = 160°), and it's constituent angles

[∠1 = ∠SOW = (x + 14)], and [∠2 = ∠WOX = (3x – 10)],

And we are required to determine the measure of ∠2.

Since, [(∠SOW + ∠WOX) = ∠SOX],

Therefore, [{(x + 14) + (3x – 10)} = 160°]

Or, [{(x + 3x) + (14 - 10)} = 160°]

Or, [(4x - 4) = 160°]

Or, [4x = (160 + 4)°]

Or, (4x = 164°)

The largest possible total area of the six pens is 33750 square feet.

Given:

An ostrich farmer wants to enclose a rectangular area and then divide it into six pens with fencing parallel to one side of the rectangle (see the figure below). there are 900 feet of fencing available to complete the job.

Let L and W  be the length and width.

900 = L + 6W

L =  900 -6W

Area = A = LW = (900-6W)W = 900W -6W^2

A' = 990-12W = 0

W = 900/12 =  75 feet wide

L = 900 -6W = 900 - 6(75)

L = 900 - 450 = 450 feet.

Maximum area = 450 * 75

Answer:

D)  0, 4, -4, -5

Step-by-step explanation:

Given polynomial:

Given (x + 5) is a factor of R(x), use long division to find the other factor:

Therefore:

[tex]R(x)=(x^3-16x)(x+5)[/tex]

Factor out x from the first factor:

[tex]R(x)=x(x^2-16)(x+5)[/tex]

Apply the Difference of Two Square Formula: a²-b²=(a-b)(a+b)

[tex]\begin{aligned}\implies x^2-16&=x^2-4^2\\&=(x-4)(x+4)\end{aligned}[/tex]

Therefore:

Zero Product Property

If a ⋅ b = 0 then either a = 0 or b = 0 (or both).

To find the zeros of the function, apply the zero-product property by setting each factor equal to zero and solving for x:

Integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer. Fractional numbers are not included in integers. Integers are represented by the symbol Z.

Since their ages are consecutive even integers, the next sibling's age would be x + 2, the next one x + 4, and the last one x + 6.

The sum of all their ages is x + (x + 2) + (x + 4) + (x + 6) = 4x + 12 = 60.

Solving for x, we get 4x + 12 = 60, and subtracting 12 from both sides gives 4x = 48.
