<u>ANSWER:
</u>
After changing the side lengths of the triangle are decreased by scale factor of 3, the perimeter of triangle also decreased by 3
<u>SOLUTION:</u>
Given, the side lengths of a triangle are decreased by a scale factor of 3.
Let the side lengths of the given triangle be a, b, c.
After the side lengths are decreased by a scale factor of 3.
Now, the side lengths will become 
Before changing the side lengths, perimeter of the triangle is p = a + b + c.
After changing the side lengths, perimeter of the triangle is 
So, the perimeter is also decreased by the scale factor of 3.
Hence, after changing the side lengths of the triangle are decreased by scale factor of 3, the perimeter of triangle also decreased by 3.

Hope this helps!
Step-by-step explanation:
Given expression is x⁴-kx²+4 =0
x−2 is a factor of the given expression.
So, x=2
Substitute in the equation, we get
2⁴-k(2)²+4
⇒16+4k+4=0
⇒4k=−20
⇒k=−5
The cost of one package of white chocolate chip cookie is $9 while the cost of one package of oatmeal cookie dough is $14.
<h3>What is an
equation?</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the cost of white chocolate chip and y represent the cost of oatmeal dough, hence:
12x + 6y = 192 (1)
Also:
6x + 12y = 222 (2)
From both equations:
x = 9, y = 14
The cost of one package of white chocolate chip cookie is $9 while the cost of one package of oatmeal cookie dough is $14.

Answer:
7/3
Step-by-step explanation:
or, 3x/4 - 7/8 = 7/8
or, 3x/4=7/8+7/8
or, 3x/4 = (7+7)/8
or, 3x/4 = 14/8
or, 3x = (14/8)*4
or, 3x=56/8
or, 3x= 7
or, x=7/3
