Those two angles are congruent(corresponding), so we can set these equal to each other.
19x+3=21x-3
-2x=-6
x=3

Factor completely 5ax2 − 20x3 2a − 8x. (a 4x)(5x2 2) (a 4x)(5x2 − 2) (a − 4x)(5x2 2) (a − 4x)(5x2 − 2).
antiseptic1488 [7]

The complete factor of the polynomial 5ax² − 20x³ + 2a − 8x is (5x² + 2) (y − 4x). Then the correct option is C.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Factor completely 5ax² − 20x³ + 2a − 8x.

Take 5x² common from the first two terms and 2 from the last two terms. we have

5ax² − 20x³ + 2a − 8x

5x²(a − 4x) + 2 (a − 4x)

Take (a - 4) common, then we have

(5x² + 2) (y − 4x)

The complete factor of the polynomial 5ax² − 20x³ + 2a − 8x is (5x² + 2) (y − 4x). Then the correct option is C.

A store owner buys a case of 144 pens for $28.80. He sells the pens for $0.40 each. The owner claims that they marked the pens u
stellarik [79]

Answer: $0.3

Step-by-step explanation:

Given

The owner buys 144 pens for $28.80 i.e. each pen costs

\dfrac{28.80}{144}=\$0.2

owner sells the pen at $0.4 i.e. price marked up by

\Rightarrow \dfrac{0.4-0.2}{0.2}\times 100=100\%

So, the claim of the owner is incorrect

The actual increase in the price to get 50% markup

\Rightarrow 0.2\times (1+0.5)=\$0.3

Please help it’s finding sin C , cos C and tan C
Aloiza [94]

The given triangle has a right angle.

We use the mnemonics SOH-CAH-TOA.

1i) \sin C =\frac{Opposite}{Hypotenuse},\implies \sin C =\frac{30}{34},\implies \sin C =\frac{15}{17}

ii) \cos C =\frac{Adjacent}{Hypotenuse},\implies \cos C =\frac{16}{34},\implies \cos C =\frac{8}{17}

\tan C =\frac{Opposite}{Adjacent},\implies \tan C =\frac{30}{16},\implies \tan C =\frac{15}{8}

2. We want to find the hypotenuse.

We know an angle to be 23 degrees.

We were also given the side opposite to this angle to be 1200km.

Therefore we use the sine ratio.

which of the following best describes a regular polygon when the measure of each exterior angle is 36 ?
zhenek [66]
<span>Even though you have no choices listed:

Each Exterior Angle = Each Central Angle = (360 degrees) ÷ (Number of Sides)
</span>Each Exterior Angle = <span>(360 degrees) ÷ (Number of Sides)
</span><span>(Number of Sides) = 360 / 36
</span><span>Number of Sides = 10
a 10-sided polygon is a decagon

A sports teacher had 1025 sweets. After distributing these equally amongst all the participants in a sports meet, he had just 1
Cerrena [4.2K]

Step-by-step explanation:

Since it remains only 1 sweet, we can subtract it from the total and get the amount of sweets distributed (=1024).

As all the sweets are distributed equally, we must divide the number of distributed sweets by all its dividers (excluding 1024 and 1, we'll see later why):

1) 512 => 2 partecipants

2) 256 => 4 partecipants

3) 128 => 8 partecipants

4) 64 => 16 partecipants

5) 32 => 32 partecipants

6) 16 => 64 partecipants

7) 8 => 128 partecipants

9) 4 => 256 partecipants

10) 2 => 512 partecipants

The number on the left represents the number of sweets given to the partecipants, and on the right we have the number of the partecipants. Note that all the numbers on the left are dividers of 1024.

Why excluding 1 and 1024? Because the problem tells us that there remains 1 sweet. If there was 1 sweet for every partecipant, the number of partecipants would be 1025, but that's not possible as there remains 1 sweet. If it was 1024, it wouldn't work as well because the sweets are 1025 and if 1 is not distributed it goes again against the problem that says all sweets are equally distributed.
