Answer:

A: 10.8

Step-by-step explanation:

AD = BC

AB = DC

2AD + 2AB

AD = ± $\sqrt{3^2+1^2}$ ≈ ±3.1622

AD ≈ 3.1622

AB = ± $\sqrt{2^2+1^2}$ ≈ ±2.236

AB ≈ 2.236

2AD + 2AB = 2*3.1622 + 2*2.236 ≈ 10.79 ≈ 10.8

What is the answer for 3x+2(4x-4)=3?

tatiyna

Answer:

<h3> $\boxed{ \bold{ \huge{ \boxed{x = 1}}}}$ </h3>

Step-by-step explanation:

$\sf{3x + 2(4x - 4) = 3}$

Distribute 2 through the parentheses

⇒ $\sf{3x + 8x - 8 = 3}$

Collect like terms

⇒ $\sf{11x - 8 = 3}$

Move 8 to right hand side and change it's sign

⇒ $\sf{11x = 3 + 8}$

Add the numbers

⇒ $\sf{11x = 11}$

Divide both sides of the equation by 11

⇒ $\sf{ \frac{11x}{11} = \frac{11}{11} }$

Calculate

⇒ $\sf{x = 1}$

Hope I helped!

Best regards!
