Answer:

The first step to solving the  equation is:

3x+24 = 42

Hence, 3x + 24 = 42 is the correct option.

Step-by-step explanation:

Given the equation

3(x+8)= 42

First of all, we need to apply the distributive law on the left side of the equation to expand the equation.

\quad \:a\left(b+c\right)=ab+ac

So the equation would be expaneded using the distributive law on the left side of the equation

3(x+8) = 42

3x+24 = 42        ∵ a(b+c) = ab + ac

Therefore, the first step to solving the  equation is:

3x+24 = 42

Hence, 3x + 24 = 42 is the correct option.

2. In the diagram below, secants PT and PU have been drawn from exterior point P such that the four arcs
scoundrel [369]

Answer:

(a) x = 30°

(b) mRS =  30°

mST =  120°

mTU  = 120°

mUR = 90°

Step-by-step explanation:

(a) In the picture attached, the diagram is shown.

Given that m arc RS = x, from the ratios:

m arc ST = 4x

m arc TU = 4x

m arc UR = 3x

The addition of the four arcs must be equal to 360°, then:

x + 4x + 4x + 3x = 360°

12x = 360°

x = 360°/12 = 30°

(b) m arc RS = x = 30°

m arc ST = 4x = 4*30° = 120°

m arc TU = 4x = 4*30° = 120°

m arc UR = 3x = 3*30° = 90°
