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]
Solve by elimination:
3x + 4y = 0
5x-3y = -58
A (6, -8)
B (-6, -8)
C (-8, 6)
D ( 8, 6)
Answer:
x=−8
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)

find the area of triangle CDE the length of the square is 24 meters;
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

The ratio of two positive numbers is 3:4. The sum
of their squares is 400. What is the sum ofthe num-
bers?
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
