2 1/2x - 3/4(2x + 5) = 3/8
5/2x - 3/2x - 15/4 = 3/8
5/2x - 3/2x = 3/8 + 15/4
x = 3/8 + 30/8
x = 33/8 or 4 1/8

Answer:

Step-by-step explanation:

Given : 212x−34(2x+5)=38.

To find : Solve for x.

Solution : We have given

212x−34(2x+5)=38.

Remove parenthesis

212 x - 68 x - 170 = 38

Solve like terms

144x - 170 = 38.

On adding both sides by 170.

144 x = 38 + 170.

144 x = 208.

On dividing both sides by 144

x = \frac{208}{144}

How many triangles can be formed with segments measuring 34 cm, 13 cm, and 38 cm? Select from the drop-down menu to correctly co
Lilit [14]

The triangle inequality theorem is not followed,  no triangle can be formed.

Triangles

In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.

The triangle inequality theorem describes the relationship between the three sides of a triangle.

According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.

Here, the sides are 34 cm, 13 cm, and 38 cm.

34cm + 13 cm = 47 cm > 38cm (theorem followed)

34 cm + 38 cm = 72 cm > 13 cm (theorem followed)

13 cm + 38 cm = 51 cm < 34 cm (theorem not followed)

Since the triangle inequality theorem is not followed,

Hence, no triangle can be formed.

Mama L [17]
The remaining area that the grass will cover will be given by:
Area=[area of rectangle]-[area of the triangle]
area of rectangle will be:
A1=length*width
=20*8
=160 square feet

The area of the triangle will be:
A2=1/2absin theta
since the triangle is equilateral, all the angles are equal and the size of each angle is 60°. Thus the area will be:
A2=1/2*5*5sin 60
=18.3
thus the remaining area of the grass will be:
Area=160-18.3
=149.7 square feet
