Answer:

$x = \sqrt{\frac{7}{2} }$

Step-by-step explanation:

<u><em>Explanation</em></u>

From given graph

AC = √7

Given angle ∝ = 45°

$cos\alpha = \frac{adjacentside}{Opposite side}$

$cos45 = \frac{x}{\sqrt{7} }$

$\frac{1}{\sqrt{2} } = \frac{x}{\sqrt{7} }$

$x = \frac{\sqrt{7} }{\sqrt{2} }$

$x = \sqrt{\frac{7}{2} }$

x = 1.8708

Which of the following is the correct usage of the distributive property of the expression: 3(x+1) ?

Alchen [17]

Answer: =3x+3

Step-by-step explanation:

$3\left(x+1\right)$

$\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b+c\right)=ab+ac$

$3\left(x+1\right)=3x+3\cdot \:1$

$=3x+3\cdot \:1$

$\mathrm{Multiply\:the\:numbers:}\:3\cdot \:1=3$

$=3x+3$
