Cubing both sides once 100%

Answer:

C on Edge2020: Cubing both sides once.

Step-by-step explanation:

In order to get rid of the radicals in the equation, we must cube both sides.

$\sqrt[3]{5x-2} -\sqrt[3]{4x} =0$ is the original equation. Cube both sides:

$5x-2-4x=0$ is what we have now that we have gotten rid of radicals.

Simplify by combining like terms and solve for $x$ .

$x-2=0$

$x=2$

Note that we have cubed both sides only once. Therefore, C is the solution.

A pet supplier has a stock of parakeets of which 20% are blue parakeets. A pet store orders 3 parakeets from this supplier. If t

Levart [38]

Answer:

0.384

Step-by-step explanation:

pet supplier has a stock of parakeets of which 20% are blue parakeets

20/100 = 0.2 blue parakeets (success)

1-0.2 = 0.8 not parakeets (not success)

A pet store orders 3 parakeets from this supplier

we need to find the chance of getting exactly one blue from 3 parakeets

$P(x=1)=nCr (p)^r(q)^{n-r}$

n=3, r=1, p = 0.2 , q=0.8

$P(x=1)=3C1 (0.2)^1(0.8)^{2}$

Twice the difference of a number + -3 is 4 find the number

NNADVOKAT [17]

Answer:

The number is 5

Step-by-step explanation:

If we need to find the hidden number, Which for simplicity's sake we will denote as "n", lets first write out the equation.

"2 x [n + (-3)] = 4"

We can work through this problem backwards. if we need two times the sum of "n" and (-3) to get to 4, the only number that can be multiplied by 2 to get a product of 4 is 2, so "n" + (-3) must equal 2. so, From here, we can figure out that since 5 + (-3) equals 2, "n" Must equal 5. so, if we plug in 5 for "n" the equation looks like this:

"2 x [5 + (-3)] = 4"

So, since the equation makes sense, the answer is, "n = 5"

Help please ill give brainliest answer

Answer:

ΔLMN ≅ ΔLQP by (SAA)

Step-by-step explanation:

It is given that line (NM) is congruent to the line (PQ), meaning they have the same measure. This is signified by the small red line on each of these sides.

Moreover, it is also given that angle (MNL) is congruent to angle (QPL), this is shown by the red arc around these angles.

Finally one can figure out that angle (NLM) is congruent to angle (PLQ) by the vertical angles theorem. The verticle angles theorem states that when two lines intersect, the opposite angles are congruent.

Thus the two triangles are congruent by side-angle-angle postulate, abbreviated as (SAA).
