Answer:

x equals 14

Step-by-step explanation:

If u plug in 14 as X. The equation would equal 180.

It's 360 feet (The person above)

Answer:

360 ft squared

Step-by-step explanation:

you have 3 (2 shapes but one is done twice)

2 rectangles and a larger rectangle

the 2 rectangles

3 is the width, and 15 is the length

15*3 = 45 * 2 (for the other one)

and you get 90ft squared

then you have the larger rectangle. it is 15 feet wide and 18 in length (15+3)

15*18 = 270

270 ft squared + 90 ft squared = 360 ft squared

Answer:

   Angle at x is 75°

Step-by-step explanation:

Data :

  Angle at A = 65°

  Angle at B = 40°

According to  the porperty of triangle we know that total interior angle a triangle has is 180° irrespect of type or size

              A + B + C = 180

      65 + 40 + C = 180

        C = 180 - 65 - 40 = 75°

Answer:

[tex]\frac{43}{2}[/tex] or 21.5

Step-by-step explanation:

8(x - 16) = 44

8x - 128 = 44

    + 128 + 128

8x = 172

/8  /8

x = [tex]\frac{43}{2}[/tex] = 21.5

To check:

8(x - 16) = 44

8(21.5 - 16) = 44

172 - 128 = 44

    44   =  44

This is a true statement, which makes our answer true.

Answer:

Step-by-step explanation:

This is a basic right angle problem relating to Pythagoras theorem as one approach.

we know.

[tex]a^2+b^2=y^2[/tex]

(letting the hypotenuse of the left triangle as y)

then,

[tex]7^2+8^2=y^2\\y=\sqrt{113}[/tex](neglecting negative root)

now since you know the value of y use the same formula to find the value of x. Keep in mind the identification of opposite , adjacent and hypotenuse sides.

Answer:

AB = 7

Step-by-step explanation:

The y-coordinate of point A and B is the same.

Therefore, both points lie on the same horizontal line (y = 2).

So determine the distance between them, subtract the x-coordinate of B from the x-coordinate of A:

AB = 4 - -3 = 4 + 3 = 7

However, to calculate the distance between 2 points, regardless if the points are on a horizontal (or vertical) line, you can always use the distance between 2 points formula that is derived from Pythagoras' Theorem, as follows:

let [tex](x_1,y_1)[/tex] = point A (4, 2)

let [tex](x_2,y_2)[/tex] = point B (-3, 2)

using the distance between two points equation:

[tex]AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\implies AB=\sqrt{(-3-4)^2+(2-2)^2}[/tex]

[tex]\implies AB=\sqrt{(-7)^2+(0)^2}[/tex]

[tex]\implies AB=\sqrt{49}[/tex]

[tex]\implies AB=7[/tex]

Product of two polynomials can be done by distribution of multiplication over addition. The product of  [tex]-2x(x^2 - 3)[/tex] is [tex]-2x^3 + 6x[/tex]

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

The product result of the given expression is

[tex]-2x(x^2 - 3) = -2x^{1 + 2} + 6x = -2x^3 + 6x[/tex]

It is because when bases are same and there is multiplication, then powers add up, so we have: [tex]a^b \times a^c = a^{b+c}[/tex]

Thus,

The product of  [tex]-2x(x^2 - 3)[/tex] is [tex]-2x^3 + 6x[/tex]

Step-by-step explanation:

the point-slope form in general is

y - y1 = m(x - x1)

where (x1, y1) are the coordinates of a point, and m is the slope.

so, we have

y - -1 = 4/3 × (x - 3)

or simplified

y + 1 = 4/3 × (x - 3)

Answer:

[tex]y + 1 =\frac{4}{3} (x-3)[/tex]

Step-by-step explanation:

We are given that a line contains the point (3, -1), and has a slope of [tex]\frac{4}{3}[/tex].

We want to write the equation of this line in point-slope form.

Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1 ,y_1)[/tex] is a point.

Since we are already given the slope and the point of the line, we can plug these values into the formula to get the equation.

Let's start with the slope; replace m with [tex]\frac{4}{3}[/tex] in the formula.

[tex]y-y_1=\frac{4}{3}(x-x_1)[/tex]

Now, replace 3 as [tex]x_1[/tex] and -1 as [tex]y_1[/tex]. Remember that the formula has subtraction in it.

[tex]y--1=\frac{4}{3} (x-3)[/tex]

This can be simplified to become:

[tex]y + 1 =\frac{4}{3} (x-3)[/tex]

Step-by-step explanation:

its a cointerior angle so the angles add up to 180

so 180 - 42 = 138

Answer:

Step-by-step explanation:

If angle 4 has a measure of 42° in the given diagram, what is the measure of angle 6?

T is a flat angle (180°)

angle 4 = angle 8

angle 2 = angle 6

180 - 42 = 138°

Answer:

The dimensions of the park on the scale drawing are 12 inches by 20 inches

The actual dimensions are given as:

Park = 600 feet by 1000 feet

Swing set = 25 feet by 100 feet

The dimension of the swing set on the scale drawing is given as: 0.5 inch by 2 inches

The above means that, the scale factor (k) is:

--- i.e. divide the scale measurement by the actual measurement

Evaluate both equations

So, we have:

Multiply the scale factor by the dimensions of the park, to get the scale measurement

Hence, the dimensions of the park on the scale drawing are 12 inches by 20 inches

The worth of the bond is $307.50.

The worth of the bond is the sum of the bond when it was bought and the interest earned on the bond.

Worth of the bond = interest rate + value when the bond was bought

Interest = 105% x $150

1.05 x $150 = $157.70

Worth of the bond = $157.70 + $150 = $307.50
