What is the value of x? The figure contains 2 lines that intersect to form what looks like an x. Two of the 4 angles in the x ar
Gnom [1K]

Answer:

x=38.5^\circ

Step-by-step explanation:

Given that the left angle = (3x-3)^\circ

The right angle across from it = 6(x-10)^\circ

The other two angles are x and x.

We know that the sum of angles at a point equals 360 degrees.

Therefore,

(3x-3)^\circ+6(x-10)^\circ+x+x=360^\circ\\3x-3+6x-60+2x=360\\11x-63=360\\11x=360+63\\11x=423\\x=38.5^\circ

The value of x is approximately 38.5 degrees.

A library building is in the shape of a rectangle. Its floor has a length of (3x + 5) meters and a width of (5x − 1) meters. The
AleksAgata [21]
The problem says that the expression (3x + 5)(5x − 1) <span>represents the area of the floor of the building in square meters. Therefore,  to solve this problem you have to follow the proccedure shown below.

 1. First, to simplify the expression (3x + 5)(5x − 1) you must apply the distributive property. Then, you obtain:

 15x</span>²-3x+25x-5

 2. Then, you have:

 15x²+22x-5

 3. As you can see, the correct answer is the last option:  15x²+22x-5
