Find perimeter and area

Answer:

x = 5

  or

x = 3

Step-by-step explanation:

The first term is,  x2  its coefficient is  1 .

The middle term is,  -8x  its coefficient is  -8 .

The last term, "the constant", is  +15

Step-1 : Multiply the coefficient of the first term by the constant   1 • 15 = 15

Step-2 : Find two factors of  15  whose sum equals the coefficient of the middle term, which is   -8 .

     -15    +    -1    =    -16

     -5    +    -3    =    -8

If the equation x²−8x−5=0 can be transformed into the equation (x−p)²=q, then value of q is 21

Two or more expressions with an Equal sign is called as Equation.

To transform the equation x² - 8x - 5 = 0 into the equation (x - p)² = q, we need to complete the square by adding and subtracting a constant term.

First, let's add 5 to both sides to get:

x² - 8x = 5

Applying complete square method

we need to add and subtract 16 inside the parentheses on the left-hand side:

x² - 8x + 16 - 16 = 5

Simplifying the left-hand side gives us:

(x - 4)² - 16 = 5

Adding 16 to both sides gives us:

(x - 4)² = 21

Therefore, the value of q is 21.

The formula for the area of the triangle is A = 1/2bh (1/2•base•height).

Identify your base and height and substitute them into the formula. Since you did not include an image or info in which states the base and height, this is what I can say.

If the base and height are 5 and 12, the area would be 30 yds. (1/2 x 5 x 12)

If the base and height are 5 and 16, the area would be 40 yds. (1/2 x 5 x 16)

If the base and height are 12 and 16, the area would be 96 yds. (1/2 x 12 x 16)

Answer:

720 m²

Step-by-step explanation:

The surface area of the prism is the sum of the areas of its 5 surfaces.

Area of triangle= ½ ×base ×height

Area of front face

= ½(6)(8)

= 24 m²

Area of back face= 24 m²

Area of rectangle= length ×breadth

Area of base

= 8(28)

= 224 m²

Area of right surface

= 10(28)

= 280 m²

Area of left surface

= 6(28)

= 168 m²

Total surface area

= 24 +24 +224 +280 +168

= 720 m²

Newton's Law of Gravitation:

Statement: According to this law, when two mass bodies are separated at finite distance then there must be an attractive force experience by them which is directly proportional to the product of their masses and inversely proportional to the square of their separation.

Consider two mass bodies m1 & m2 be kept at distance d. Then the force of attraction F is given as

                                 [tex]Fa1/d^2[/tex]

Now, from above equations, we have

                          [tex]Fa\frac{m_{1}m_{2}}{d^2}[/tex]

or,                           [tex]F=G\frac{m_{1}m_{2}}{d^2}[/tex]

Here         [tex]G=6.67*10^{-11}Mm^2kg^{-2}[/tex]   is the universal gravitational constant.

The length of the hypotenuse AB is equal to the sum of the square of other two sides AC and BC. The measure of the curve DE is 10.5 units

The theorem states that the length of the hypotenuse AB is equal to the sum of the square of other two sides AC and BC.

According to the theorem;

AB^2 = AC^2 + BC^2

AB^2 = 6^2 + 8^2

AB^2 = 36 + 64

AB = 10

If the curve DE is 5% longer than line segment АВ, the measure of curve DE is given as;

DE = 1.05 * 10
DE = 10.5

Hence the measure of the curve DE is 10.5 units

Using linear function concepts, it is found that:

A linear function is modeled by:

y = mx + b

In which:

For Fast Freedy, we have that he run one mile in four minutes, hence the slope is given by:

mF = 1/4 = 0.25 miles per minute.

The constant speed of Fast Freddy is of 0.25 miles per minute.

For Speedy Sam, when the the time changes by 16 minutes, the distance changes by 2, hence his slope is given by:

mS = 2/16 = 1/8 = 0.125 miles per minute.

The constant speed of Speedy Sam is of 0.125 miles per minute. Hence, due to the higher speed, Fast Freedy ran faster.

If the question is [tex]2x^{2} -18x+65[/tex] then the answer is no real solution. If the question is 2x - 18x + 65 than the answer is -16x+65

Answer:

x = 13, 5

Step-by-step explanation:

x² - 18x + 65 = 0

step 1: multiply (1) and (65) together

step 2: find two negative numbers to add together to equal -18 but multiply together to equal 65.

step 3: since there isn't a number in front of x² you could:

(x - 13) (x - 5)

x - 13 = 0           x - 5 = 0

   +13  +13            +5   +5

x = 13                      x = 5

or

(x² - 13x) (-5x + 65)

x(x - 13) -5 (x - 13)

(x - 13) (x - 5)

x - 13 = 0      x - 5 = 0

  +13   +13       +5   +5

x = 13, 5

Answer:

[tex]y =\dfrac{12}{5}x + 22[/tex]

Step-by-step explanation:

Slope-intercept form of line:

First find the slope of the line AB. ie, m

Slope of the perpendicular line = -1/m

(2 , 3)  ⇒ x₁ = 2 & y₁ = 3  

(-10, 8)  ⇒ x₂ = -10 & y₂ = 8

[tex]\boxed{Slope=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

          [tex]= \dfrac{8-3}{-10-2}\\\\=\dfrac{5}{-12}\\\\=\dfrac{-5}{12}[/tex]

[tex]\sf slope \ of \ the \ perpendicular \ line \ m_1 = \dfrac{-1}{m}= -1 \ \div \dfrac{-5}{12}[/tex]

                                                   [tex]\sf = -1 * \dfrac{12}{-5}=\dfrac{12}{5}[/tex]

Equation of the required line: y = mx + b

       [tex]y =\dfrac{12}{5}x+b[/tex]

The line passes through (-5 , 10). Substitute in the above equaiton,

         [tex]10 =\dfrac{12}{5}*(-5) + b\\\\ 10 = (-12) + b\\\\[/tex]

 10 + 12 = b

        b   = 22

Equation of the line:

  [tex]y =\dfrac{12}{5}x + 22[/tex]

Explanation:

The arc markings for each angle show that we have two pairs of congruent angles (angle O = angle Q, angle M = angle R). This takes care of the two "A"s in "ASA". The tickmarks show us that the sides MO and RQ are the same length, so this takes care of the "S" of "ASA". Note the congruent sides are between the angles mentioned. The order is important.
