4 0

Answer:

15 and 270

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{a} = a

\sqrt[3]{a} × \sqrt[3]{a} × \sqrt[3]{a} = a

(a)

Given

(\sqrt{5} )² × (\sqrt{3} )²

= 5 × 3

= 15

(b)

Given

(\sqrt[3]{9} )³ × (\sqrt{30} )²

= 9 × 30

= 270

Write an equation in slope-intercept form of the line with slope −4/5 that contains the point (−5, −4).
Tomtit [17]
From the slope our equation so far is
y = -4/5x + B
Now we find B
-------------------------
To find be all we have to is substitute (-5,-4) for x and y in <span>3x + 5y = 15 
</span>(-4) - (-4/5)( -5) = b
-8 = b
---------------------------------
So your equation would be y = -4/5x - 8

Otero translated the phrase “three less than a number” into the expression 3-x. Which best describes the accuracy of Otero’s exp
xz_007 [3.2K]

Answer:

Option B is correct.

Step-by-step explanation:

Otero translated the phrase "three less than a number" into the expression 3 - x.

I think Otero gave a wrong expression for the phrase.

The true interpretation of the phrase is that if we assume the number as x then three less than a number means x - 3.

Therefore, Otero's expression is inaccurate. Three is being subtracted from a number, so x-3 is what he should have written. (Answer)

What is the value of x?​
alina1380 [7]

Answer:

<h2>x = 4</h2>

Step-by-step explanation:

Look at the picture.

We have the triangles 30° - 60° - 90° and 45° - 45° - 90°.

The sides are in proportions:

30° - 60° - 90° ⇒ 1 : √3 : 2

45° - 45° - 90° ⇒ 1 : 1 : √2

======================================================

SR=ST\sqrt3\to ST\sqrt3=2\sqrt3\qquad\text{divide both sides by}\ \sqrt3\\\\ST=2\\\\TR=2ST\to TR=2(2)=4\\\\RQ=TR\to RQ=4\to x=4
