Do the side lengths 15,20 and 25 form a right triangle? PLEASEEEE HELPPPP!!! asap

sveticcg [70]

<h3>Answer: Yes, those sides form a right triangle</h3>

===================================================

Work Shown:

a^2+b^2 = c^2

15^2+20^2 = 25^2

225+400 = 625

625 = 625

Since the last equation is true, this makes the first equation true for those a,b,c values. Therefore, by the pythagorean theorem converse, this is a right triangle.

Side note: c is always the longest side.

olganol [36]

Answer:

a = 16

b = 10

In the equation from the question there's no value that you can determine for c.

Step-by-step explanation:

(4x)(3z+y)+2x(3y+2z)=axz+bxy
12xz+4xy+6xy+4xz
16xz+10xy

Left to Right

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (5, 9)

Point (-3, 9)

Step 2: Identify

x₁ = 5, y = 9

x₂ = -3. y = 9

Step 3: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{9-9}{-3-5}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{0}{-8}$
[Slope] [Fraction] Divide: $\displaystyle m=0$
