The length of the sides of a triangle are x, 2x+2, and 13. If the perimeter of the triangle is 30, what is the value of x?

scZoUnD [109]

Add all the sides up to equal 30 in an equation because you are given the perimeter. The perimeter is the length around a two dimensional shape. This means the perimeter is the length of all the side lengths added together.

(x) + (2x + 2) + (13) = 30

Combine like terms.

3x + 15 = 30

Subtract 15 from both sides.

3x = 15

Divide both sides by 3.

$\boxed {x = 5}$

Given

The two communication mask are 2 km apart

Ubi's home is 500 m east of one of the mask

Suppose its distance from the other's is x

From the figure, we can write

$\Rightarrow x^2=2000^2+500^2\\\Rightarrow x^2=4\times 10^6+25\times 10^4\\\Rightarrow x=2061.55\ m\ \text{or}\ 2.061\ km$

Given

Its a cylindrical vase .
Radius = 2 inches
height = 8 inches .

Formula

$\bold { \purple {volume = \pi \: {r}^{2}h \: }}$

Lets assume pi to be 3.14

$v = 3.14 \times {2}^{2} \times 8 \\ \\ \\ v = 3.14 \times 4 \times 8 \\ \\ \\ v = 3.14 \times 32 \\ \\ \\ v = 1008.48 {in}^{2}$
