Answer:

(2x+3) y (3x+5)

Step-by-step explanation:

For this exercise we have that the volume is

V = 6x ^ 3 + 31X ^ 2 + 53x + 30

H = X + 2

The formula for the Volume its

V = H * L * W

for find L and W (width and length) we divide V / H = L * W

So,

\frac{V}{H} =\frac{6X^{3}+31X^{2}+53X+30 }{X+2}=(2x + 3) * (3x + 5)\\

this division is in the attachment

so, L * W = (2x + 3) * (3x + 5)

Solve for x. Round to the nearest hundredth.
Airida [17]

Answer: 32.98^{\circ}

Step-by-step explanation:

Since, By the given diagram,

In quadrilateral ABCD, all angles are right angles ⇒ DC = AB = 15 cm and CB = DA

Also, In triangle DFA,

sin 56^{\circ} = \frac{DA}{DF}

⇒ sin 56^{\circ} = \frac{DA}{16}

⇒ 16\times sin 56^{\circ}=DA

⇒ 13.2646011609\text{ cm} = DA

Now, In triangle, DEC,

tan x = \frac{EC}{DC}

⇒ tan x = \frac{EB-CB}{DC}

⇒ tan x = \frac{EB-DA}{DC}

⇒ tan x = \frac{23-13.2646011609}{15}  

⇒ tanx = \frac{9.73539883912}{15}

⇒ tanx = 0.64902658927

⇒ x = 32.9846428556^{\circ} \approx 32.98^{\circ}

Is (-8,7), (0,1), (2,-6), (2,3), (7,9) a function?<br> What’s the domain and range?
Juliette [100K]
No it is not a function because the 2 repeats and for it to be a function none of the x values can repeat.

The domains are -8, 0, 2, 2, 7 (when it asks for domain it is asking for the x values)

The ranges are 7, 1, -6, 3, 9 (when it asks for range it is asking for the y values)

Giving brainliest for correct awnser. Factor the expression below. <br>​
tresset_1 [31]

Answer:

B. (x + 3) (x + 27)

Step-by-step explanation:

<em><u>To factor the expression, you must split the middle term (18x) into two terms that can be added to get 18, and multiplied to get 81:</u></em>

<em><u /></em>x^2 + 18x + 81

x^2 +3x + 27x + 81

<em><u>Group:</u></em>

<em><u /></em>(x^2 +3x) (27x + 81)

<em><u>Take out GCF (Greates Common Factor):</u></em>

x(x + 3) 27(x + 3)

(x + 27) (x + 3)
