Answer:
x = 9.7
Step-by-step explanation:
The area of a triangle is A = b * h / 2 where A, b, and h are the area, base and height respectively. We know that A, b, and h equal 47, x, and x respectively so we can write:
47 = x * x / 2
47 = x² / 2
94 = x²
x = ±√94
In context, x can't be negative so the answer is x = √94 = 9.7.
Answer: (3, -1)

Reflecting over y = -x maps
.
So, 
The weight of galss cube with side 5 cm is 300 grams
<em><u>Solution:</u></em>
A glass cube is of side length 5 cm
Let us first find the volume of glass cube
<em><u>The volume of cube is given as:</u></em>

Thus volume of cube is 125 
Given that,

So, weight of 125 cubic centimeter of glass cube is found by multiplying weight of 1 cubic centimeter of glass cube by 125


Thus weight of galss cube with side 5 cm is 300 grams
Answer:
x = -7
Step-by-step explanation:
2x+6 = x-1
add -6 to both sides
2x = x-7
add -x to both sides
x = -7
