What is the factored form of 64g^3+8?

1 answer:

7 0

64 = 4 x 4 x 4 g^3 = g x g x g the problem is the sum of of 2 cubes 8 = 2 x 2 x 2 so the factored form is - a3+b3=(a+b)(a2−ab+b2).

What is the length of AC?

Otrada [13]

Answer:

Length of AC = 12units.

Step-by-step explanation:

$\sf\large{\star Given:-}$

Hypotenuse of the triangle = $\sf\pink{10\:units.}$
Height of the triangle = $\sf\pink{8 \: units.}$

$\sf\large{\star To\: Find:-}$

$\rightarrow$ Base of the triangle.

$\sf\large{\star Solution:-}$

$\rightarrow$ As we know that,

Pythagoras Theorem:

$\sf\blue{Hypotenuse^2\:=\: Height^2+Base^2}$

So, In triangle ABD by putting the value of hypotenuse and height in this formula we get,

$\rightarrow$ $\sf{10^2\:=\: 8^2 + Base^2}$

$\rightarrow$ $\sf{100\:=\: 64 + Base^2}$

$\rightarrow$ $\sf{100-64\:=\: Base^2}$

$\rightarrow$ $\sf{36\:=\: Base^2}$

$\rightarrow$ $\sf{\sqrt{36}\:=\: Base}$

$\rightarrow$ $\sf{6\:=\: Base}$

Since, it is given that BD is the perpendicular bisector of AC so length of AC will be doubled.

Therefore, length of AC of the given triangle = $\sf\purple{12units.}$

Find the missing values of the variables. The diagram is not to scale. Show steps

earnstyle [38]

Step-by-step explanation:

i assume this is the question you asked me to look at.

Well, angle 116° and y are supplementary angles

therefore,116°+y=180°

y=180°-116°=64°

Now to find x

x+y+125+72=360°

x+64+125+72=360

x+261=360

x=360-261=99°
