Answer:

No, the work is not correct. The distributive property was not used properly to expand the expression. Negative 6 should be multiplied by both terms in the parentheses. The second product should be -6 times -2/13 to get positive 12/13.

Answer:

No.

Step-by-step explanation:

Honestly, I'm not entirely certain. The steps are formatted very weirdly and I'm not sure what they are.

I believe the first step is -6(4x-213) which is a different expression than the last step which is (-24x-1213) but those aren't very similar.

Find x. \/3 1.5 3 \/3 2

serg [7]

$x = \sqrt{3}$

Step-by-step explanation:

Given:

$\sin(ABC) = \frac{AC}{AB}$

$= > \sin(60) = \frac{3}{AB}$

$= >AB= 2 \sqrt{3}$

Now by Pythagoras theorem,

$AC^{2} + BC^{2} = AB^{2}$

Substituting values,

${3}^{2} + {x}^{2} = (2 \sqrt{3})^{2}$

$= > {x} = \sqrt{3}$

Hence, value of x is $\sqrt{3}$

An automobile engineer is revising a design for a conical chamber that was originally specified to be 12 inches long with a circ

icang [17]

The scale factor is 1.5, which means that the revised chamber is larger. The new dimensions are just the old dimensions times 1.5.

The volume of the revise chamber is:

V = (1/3) (PI) [(D/2)^2] (H)

= (1/3) (PI) {[(5.7)(1.5)/2]^2} [(12)(1.5)]

= 344.4874 in3

What is the value of x? Enter your answer in the box

Natalija [7]

In similar triangles the ratio of the corresponding sides is equal.
Therefore in this case; the two triangles are similar;
hence;
5 in/ 15 in = 8 in / x
Where x is the unknown side
x= (8 × 15)/5
= 120/5
= 24 in
Therefore, the value of x is 24 inches
