How do you factor 8y^3+316

PilotLPTM [1.2K]

8y^3+316
divide both sides by 4 (smallest divisable number) just say you tried to factor 2 and 3 and they weren't whole numbers and then you tried 4 and gave you the answer :)
4(2y^3+79)

The diameter of a cylinder is 1 yd. The height is 8 yd. What is the first step to finding the volume of the cylinder? Find the

Talja [164]

Answer:

D

Step-by-step explanation:

you find the radius by using the diameter

hence radius = diameter divide by 2 which is 1÷2 which is 0.5

next step the volume of the cylinder is πr^ 2h

22÷7 × 0.5×0.5×8 gives you 6.2857 to 5 significant number

2/3 minus 5/8<br> what’s the answer

Rama09 [41]

Hey there!

$\frac{2}{3}$ $-$ $\frac{5}{8}$
Change the " $subtract$ " symbol to a $addition$ symbol
$\frac{2}{3} + \frac{-5}{8}$
$(-5)(3)$ $= -15$
$2(8)$ $=16$
$3$ $(8)$ $=$ $24$
$\frac{16}{24} + \frac{-15}{24}$
Add " $16 + (-15)$ " together
$\frac{16+ (-15)}{24}$
$16 + (-15)$ $= 1$
$24$ $= 24$
Therefore, $\boxed{Answer: \frac{1}{24} }$

Good luck on your assignment and enjoy your day!

Someone help ASAP!!!!!!

Alchen [17]

Answer:

Length, l = 11 ft.

Width, w = 9 ft.

Step-by-step explanation:

From the given data, the area of the rectangle = 99 ft².

Area of the rectangle = Length, l X Width, w

Here, Length, l = 7 more than twice the width

⇒ Length, l = 7 + 2w

Therefore, Area, A = 99 = (7 + 2w)w

⇒ 99 = 7w + 2w²

⇒ 2w² + 7w - 99 = 0

Solve the Quadratic equation using the formula: x = $\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$ for the quadratic equation ax² + bx + c = 0.

Therefore, w = $\frac{-7 \pm \sqrt{7^2 -4(2)(-99)}}{2(2)}$

$= \frac{-7 \pm \sqrt{49 + 8(99)}}{4}$

$= \frac{-7 \pm + \sqrt{841}}{4}$

Since, $\sqrt{841} = 29$ we get:

$w = \frac{-7 \pm 29}{4}$

This gives two values of 'w', viz., w = $\frac{-7 - 29}{4}$ , $\frac{-7 + 29}{4}$

$\implies w = \frac{22}{4}, \frac{-36}{4}$

⇒ w = $\frac{22}{4}$ , -9.

We take the integer values.

If w = -9, then l = 2(-9) + 7

⇒ l = - 18 + 7 = - 11

Therefore, the length, l of the rectangle = - 11 ft.

and the width, w of the rectangle = - 9 ft.

Hence, the answer.
