Find the surface area

Answer:

its 5/6

Step-by-step explanation:

we just group things around and we have this

36 m^2 - 60 m = -25

Alternate forms:

12 m (3 m - 5) = -25

36 m^2 - 60 m + 25 = 0

Solution:

m = 5/6

Answer:

8

Step-by-step explanation:

sqrt8*sqrt8 = sqrt8^2 = 8

Answer:

short side = 4

Step-by-step explanation:

area = 1/2BH

18 = 1/2(x - 1)(x + 4)

18 = 1/2(x² + 4x - x - 4)

multiply both sides of the equation by 2:

36 = x² + 3x - 4

x² + 3x - 40 = 0

(x + 8)(x - 5) = 0

x = 5

short side = 5 - 1 = 4

The shortest length of the right angled triangle is 4 cm.

where

b = base

h = height

Therefore,

area = 18 cm²

18 = [tex]\frac{1}{2}[/tex] × (x - 1)(x + 4)

36 = (x - 1)(x + 4)

x² + 4x - x - 4 = 36

x² + 3x - 4 = 36

x² + 3x - 4 - 36 = 0

x² + 3x - 40 = 0

x² - 5x + 8x - 40 = 0

x(x - 5) + 8(x - 5) = 0

(x + 8)(x - 5) = 0

x = -8 or 5

we can only use positive numbers.

Therefore,

x = 5

The shortest sides is definitely one of the 2 legs . The hypotenuse of a triangle is the longest side.

Therefore,

h = x - 1 = 5 - 1 = 4 cm

b = x + 4 = 5 + 4 = 9 cm

The perimeter of a triangle is (x+10)/(x+3) units.

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.

The sides of given triangle are 2/(x-3), (x²-21)/(x²-9) and 5/(x+3).

Perimeter = 2/(x-3) + (x²-21)/(x²-9) + 5/(x+3)

= 2(x+3)/(x²-9) + (x²-21)/(x²-9) + 5(x-3)/(x²-9)

= (2x+6+x²-21+5x-15)/(x²-9)

= (x²+7x-30)/(x²-9)

= (x²+10x-3x-30)/(x²-9)

= (x(x+10)-3(x+10)/((x-3)(x+3))

= ((x+10)(x-3))/((x-3)(x+3))

= (x+10)/(x+3)

Therefore, the perimeter of a triangle is (x+10)/(x+3) units.

Answer:

[tex]g(x) = \frac{6}{5}x + 8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 6x + 8[/tex]

[tex]k = 5[/tex] --- horizontal stretch factor

Required

Find g(x)

When a function is stretched horizontally by k, the resulting function will be:

Rule: [tex]g(x) = f(\frac{1}{k}x)[/tex]

So, we have:

[tex]g(x) = f(\frac{1}{5}x)[/tex]

Solve for: [tex]f(\frac{1}{5}x)[/tex]

[tex]f(\frac{1}{5}x) = 6 * \frac{1}{5}x + 8[/tex]

[tex]f(\frac{1}{5}x) = \frac{6}{5}x + 8[/tex]

Recall that:

[tex]g(x) = f(\frac{1}{5}x)[/tex]

[tex]g(x) = \frac{6}{5}x + 8[/tex]

Answer:

f(1/5x) = 6 ^1/5x  +8

A horizontal stretch by a factor of 5 means that the input, or x, is multiplied by : 1/5

Step-by-step explanation:

Hello!

Here we are given a composite shape, meaning that we can divide this shape up into ways that we are given formulas to solve for legs and such.

I can see here that this can be divided into a triangle and a rectangle using a horizontal line.

The leg lengths of this triangle would be 9, because it is congruent to the bottom side of the rectangle, and 7, because it is the left side minus the right side.

This would also make a right triangle, meaning we could solve for the hypotenuse utilizing the Pythagorean Theorem.

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

[tex]6^2+7^2=c^2[/tex]

[tex]36+49=c^2[/tex]

[tex]c^2=85[/tex]

[tex]c=\sqrt{85}[/tex]

Which is in simplest radical form.

Answer:

Step-by-step explanation:

The central angle and the angle between the tangents are supplementary, so

x + 26° = 180° ( subtract 26° from both sides )

26 - 26 = 0

180 - 26 = 154

x = 154°

6x + 3x = 180

9x = 180

Answer:

442

Step-by-step explanation:

625-183=442

The more miles he have to drive is 442miles.

We have given that,Jon is taking a 625 mile trip.On the first day, he drove 183 miles.

We have to find the how many more miles does he have to drive.

Total distace mile drove =mile drove first day+Remaining drove in miles

So we can write it as,

Total distance  miles-Miles drove first day= Remaining miles

Total distance=625

first day distance=183

Remaining distance

=625-183

=442

Therefore the remaining distance is 442miles.
