Answer:

Step-by-step explanation:

HEllo,

$(\sqrt{3})^n=3^{\frac{n}{2}}=\dfrac{3^x}{27^y}=3^x\times(3^3)^{-y}=3^{x-3y}\\\\\dfrac{n}{2}=x-3y\\\\\boxed{\sf \bf n= 2x-6y}$

Hope this helps

19. Find the value of X (In the picture) (giving points to best answer/brainlest)

Tema [17]

Answer:

x = 61 degrees

Step-by-step explanation:

The triangle on the right is isosceles and the base angles are congruent

the sum of the inner angles of a triangle is 180 degrees

2 * 74 + y = 180

148 + y = 180

y = 32 degrees

the total angle is 90 degrees

so we have that

90 - 32 = 58 degrees

Also the left triangle is isosceles, so we have

2x + 58 = 180

2x = 122

x = 61 degrees

Can someone please help me with this geometry question

goldenfox [79]

Answer:

A. q = 39

Step-by-step explanation:

Since the lines are parallel, their sides will be proportional,

So,

Taking their proportion

=> $\frac{60}{40} = \frac{q}{26}$

Cross Multiplying

q × 40 = 26 × 60

q = $\frac{1560}{40}$

q = 39

HI yeah its me again

damaskus [11]

Answer:

$4\sqrt[3]{7x}$

Step-by-step explanation:

Look for the same stuff under the radical symbol. Here, that "stuff" is "7x". Only one answer choice has 7x under the radical.

_____

Here, there are no cubic factors under the radical that can be factored out—either in the problem expression or in the answer choices. If there were cubic factors, you'd want to remove them before making the comparison.

For example, ∛(56x) would be a like radical to ∛(7x) because a cubic factor of 2^3 = 8 can be removed to make it be 2∛(7x).

The ratio of the length to the width of a rectangle is 5:4. The length of the rectangle is 60 inches. What is the width?

Firlakuza [10]

$\huge\boxed{\text{48 inches}}$

We know that $\frac{\text{length}}{\text{width}} = \frac{60}{\text{width}} = \frac{5}{4}$ .

Solve using cross multiplication of the last two fractions. I will use $w$ to represent the width of the rectangle. $60*4=w*5$

Multiply. $240=5w$

Divide both sides of the equation by $5$ . $\boxed{48}=w$
