One side of a triangle is half the longest side. The third side is
Illusion [34]

Answer:

The length of the sides are 9 units, 18 units and 11 units

Step-by-step explanation:

Let

x ----> one side of the triangle

y ----> the longest side of the triangle

z ----> the third side of the triangle

we know that

The perimeter of triangle is equal to

P=x+y+z

we have

P=38\ units

so

38=x+y+z ----> equation A

x=\frac{y}{2} -----> equation B

z=y-7 ----> equation C

substitute equation B and equation C in equation A

38=\frac{y}{2}+y+(y-7)

solve for y

38=\frac{5}{2}y-7

\frac{5}{2}y=38+7

\frac{5}{2}y=45

y=45(2)/5

y=18\ units

<em>Find the value of x</em>

x=\frac{y}{2} ---> x=\frac{18}{2}=9\ units

<em>Find the value of z</em>

z=y-7 ----> z=18-7=11\ units

therefore

The length of the sides are 9 units, 18 units and 11 units

kondaur [170]

The domain of a function is the set of all the x terms of the function and the range of a function is the set of all the y terms of a function.

For example, take a look below.

The domain is the set of all x terms in each ordered pair and the

range will be the set of all the y terms in each ordered pair.

What is the surface area of a box if it is scaled up by a factor of 10
xenn [34]
If we are scaling up the surface area by a factor of 10 means that the two dimensions of area are each being increased by 10 times the original size. Therefore, the surface area is increased by a factor of 10 x 10, or by a factor of 100.
