Answer:
a.x=4
b.x=4
c.(b)
Step-by-step explanation:
We are given that

a. First we adding x on both sides we get


Now, subtract 5 on both sides we get


b.
We are subtracting 9 from both sides we get



We can solve equation both approach a and b
But I prefer (b) because in approach (b)
There are only 3 step in which we can get answer but in approach (a) we can get answer in 4 steps .
Hence, I prefer approach (b)
*Remember that slope : is y=mx+b
And m is slope and b is the y-intercept -
In this equation y-6=2(x+3)
m is 2 because if u multiply 2 to (x+3) it will become 2x+6
since m is 2 and b is 6
The slope is 2
And the y-int. is 6
So the slope is 2.
Answer:
Use the view example tool
Step-by-step explanation:
Use the view example tool and just plug in your number's instead of theirs. I did the same and I got it right.
The length of side DE is 3cm
<h2 /><h3>Parallel line</h3>
Since the line AC is equivalent to DE, hence AC = DE
To get the length of DE, we will need to get the length oF AC using the Pythagoras theorem:
Given the following parameters
Hypotenuse = 5
Opposite = 4
Required
Adjacent side
Substitute the given parameters into the formula of Pythagoras theorem.
AC² = 5² - 4²
AC² = 25 - 16
AC² = 9
AC = 3
Hence the length of side DE is 3cm

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
