Solve for the x in the equation <br><img src="https://tex.z-dn.net/?f=x%20%2B%203x%20%2B%205x%20%2B%207x%20%2B%20...49x%20%3D%20

Flauer [41]

Answer:

x=1

Step-by-step explanation:

x+3x+5x+7x+...+49x=625

(1+3+5+7+...+49)x=625 (1)

now consider s= 1+3+5+7+...+49

a=1

d=3-1=2

l=49

l=a+(n-1)d

49=1+(n-1)2

49-1=(n-1)2

48/2=n-1

n-1=24

n=24+1=25

s=n/2*(a+l)

s=25/2(1+49)

x=25/2×50

s=25×25=625

from (1)

625 x=625

x=625/625=1

What is the lateral area of the cone?

ale4655 [162]

The diameter of the base of the cone is 6 units, thus the radius of it is 3 then.

$\bf \textit{lateral area of a cone}\\\\
LA=\pi r\sqrt{r^2+h^2}~~
\begin{cases}
r=3\\
h=5
\end{cases}\implies LA=\pi (3)\sqrt{3^2+5^2}
\\\\\\
LA=3\pi \sqrt{34}$

TEA [102]

Answer:

(E) 9

Step-by-step explanation:

I found what numbers worked in all three cases. I found that when a = 4 b = 5 c = 0, all of the equations were satisfied.

Equation 1 4 + 5 = 9

Equation 2 4 + 0 = 4

Equation 3 5 + 0 = 5

Also, a + b+ c or 4 + 5 + 0 = 9

If these answers are correct, please make me Brainliest!

Answer:

∴ 2nd equation can be used to determine the length of other leg.

Which is known as $a=\sqrt{13^{2}-12^{2}}$

Step-by-step explanation:

Given,

A Right Triangle has hypotenuse of $13$ units and one leg has $12$ units.

We know Pythagoras Formula for Right Triangle;

$Hypotenuse^{2} =Perpendicular^{2} +Base^{2}$

Here hypotenuse and one leg values in above equation and take $Base=a$ ;

$13^{2} =12^{2} +a^{2}$

$a^{2} =13^{2} -12^{2}$

$a=\sqrt{13^{2}-12^{2}}$

So 2nd equation can be used to determine the length of other leg.
