Answer:

Step-by-step explanation:
The equation;
÷ x - 4
Factor;
÷ ( x - 4 )
Rewrite in fraction form, so that one can perform division

Simplify, cancel out like terms on opposite sides of the fraction bar

Answer: A. 72
Explanation: 15 + 25 + 10 = Total of marbles = 50
10/50 10 Marbles out of 50 total marbles
10/50 = ?/360
360 / 50 = 7.2
7.2*10= 72
72/360 so yeah it’s 72

Answer: 
Step-by-step explanation:
You need to remember the following:
1. The area of a rectangle can be calculated with the following formula:

Where "l" is the length and "w" is the width.
2. The area of a triangle can be calculated with the following formula:

Where "b" is the base and "h" is the height.
Use those formulas to find the area of each face.
<u> Area of the rectangle</u>

<u>Area of two triangles</u>
There are two equal triangles. Each one has a base of 10 inches and a height of 5 inches. Then, their areas are equal:

The areas of the other two triangles (which are equal) are:

Adding the areas of the faces, you get that the surface area of the rectangular pyramid is:

Step-by-step explanation:
x+3y=-4(eqn1)
x=-4-3y
from (eqn 2)
2(-4-3y)+6y=5
-8-6y+6y=5
y=5+8=13.
y=13
from eqn 1
x+3(13)=-4
x+39=-4
x=-4-39
x=-43.
