Yes. We’ll always be able to connect the points at the end of each side to form the triangle’s third side, no matter what the lengths or angles.

2 1/4(4x-1)=1 3/5(1+4x)?? I need help with this problem. Thanks!!

Solving $2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)$ we get $x=\frac{77}{52}$

Step-by-step explanation:

We need to solve the problem: $2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)$

Solving:

$2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)\\\frac{9}{4}(4x-1)=\frac{8}{5}(1+4x)\\9x-\frac{9}{4}=\frac{8}{5}+\frac{32x}{5}$

Add 9/4 on both sides:

$9x-\frac{9}{4}+\frac{9}{4}=\frac{8}{5}+\frac{32x}{5}+\frac{9}{4}$

$9x=\frac{8}{5}+\frac{9}{4}+\frac{32x}{5}\\9x-\frac{32x}{5}=\frac{8}{5}+\frac{9}{4}\\\frac{9x*5-32x}{5}=\frac{8*4+9*5}{20}\\\frac{45x-32x}{5}=\frac{32+45}{20}\\\frac{13x}{5}=\frac{77}{20}\\x=\frac{77}{20}\times \frac{5}{13}\\x=\frac{77}{4*13}\\x=\frac{77}{52}$

So, Solving $2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)$ we get $x=\frac{77}{52}$

Which polynomial is a difference of two squares? O x² – 16 O x² +16 O x² – 8 O x² + 8

UNO [17]

Answer:

x²-16

Step-by-step explanation:

x²-16 =0

Add 16 to both sides

x²-16 + 16 = 0 + 16

Simplify

x²= 16

For x²=(fa) the solutions are x = √(fa), -√(fa)

X=√16 ,X= -√16

√16=4

-√16 = -4

x=4, x= -4

Consider lines An and CD

vichka [17]

Answer:

slope of AB = 2

slope CD = 2

Step-by-step explanation:

the equation of a line is y = ax+ b where a is the slope, b is the y-intercept

let us take yB - yA

→ yB - yA = axB <u>+ b</u> - axA <u>- b</u>

→ yB - yA = a(xB - xA)

→ a = (yB - yA) / (xB = xA) = (6 - 2) / (-5 - (-7)) = 2

same goes for line CD
