Answer:

9 and 3

Step-by-step explanation:

if we multiply 9 and 3 we get 27

also when we add 9+3= 12

Step-by-step explanation:

Step-by-step explanation:

Answer:

12 and 16.

Step-by-step explanation:

Let both positive numbers be x and y.

3/4 = x/y....... equation 1

x² + y² = 400..... equation 2

From equation 1

3/4 = x/y

Cross multiply

3y = 4x

Divide both sides by 3

y = 4x/3

Substitute y = 4x/3 into equation 2

x² + y² = 400

x² + (4x/3)² = 400

x² + 16x²/9 = 400

Multiply through by 9

9x² + 16x² = 3600

25x² = 3600

Divide both sides by 25

x² = 3600/25

x² = 144

Take the square root of both sides

x = √144

x = 12

Substitute x = 12 into equation 1

3/4 = x/y

3/4 = 12/y

Cross multiply

3y = 12 x 4

3y = 48

Divide both sides by 3

y = 48/3

y = 16

Answer:

pythagorean theorem!

Step-by-step explanation:

a²+b²=c² (normal)

a²=c²-b² (to find a)

[tex]a { = \sqrt{c {}^{2} } } - b ^{2} [/tex]

[tex]a = 38 ^{2} - 27 ^{2} [/tex]

[tex]a = \sqrt{1444 - 729} [/tex]

[tex]a = \sqrt{715} [/tex]

[tex]a = 26.7394839142[/tex]

Answer:

288

Step-by-step explanation:

If you didnt know a triangle has the area of a square/2

so basically what im saying is the area of that square/2 equals the area of the triangle

to find the area of the square you take 24 and square it

24^2=576

finally we divide that by 2

576/2=288

so the area of the triangle is 288

have a great day :D

Answer: 2t + 10

Step-by-step explanation:

2t represents the number of triangles and 10 bookends the sides of the triangle(s). Notice in the picture each triangle base has a value of two, no matter how many triangles are grouped together. Now notice that no matter how many triangles are grouped together, 5 will always be on the left and right of the final picture.

The angles that are alternate interior angles are; ∠ONQ and ∠MNQ

Alternate interior angles are defined as the angles that are formed when a transversal intersects two coplanar lines.

Answer:

y=6=

Step-by-step explanation:

3x+4y=0

5x−3y=−58

In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

3x+4y=0,5x−3y=−58

To make 3x and 5x equal, multiply all terms on each side of the first equation by 5 and all terms on each side of the second by 3.

5×3x+5×4y=0,3×5x+3(−3)y=3(−58)

Simplify.

15x+20y=0,15x−9y=−174

Subtract 15x−9y=−174 from 15x+20y=0 by subtracting like terms on each side of the equal sign.

15x−15x+20y+9y=174

Add 15x to −15x. Terms 15x and −15x cancel out, leaving an equation with only one variable that can be solved.

20y+9y=174

Add 20y to 9y.

29y=174

Divide both sides by 29.

y=6

Substitute 6 for y in 5x−3y=−58. Because the resulting equation contains only one variable, you can solve for x directly.

5x−3×6=−58

Multiply −3 times 6.

5x−18=−58

Add 18 to both sides of the equation.

5x=−40

Divide both sides by 5.

x=−8

The system is now solved.

x=−8,y=6

Coordinates are: (-8,6)
