Mia is factoring the polynomial x2 + 4x – 12. She uses the steps shown.
A 2-column table with 4 rows. The first column has no label with entries Step 1, Step 2, Step 3, Step 4. The second column is labeled x squared + 4 x minus 12 with entries x squared + 6 x minus 2 x minus 12, (x squared + 6 x ) minus (2 x + 12), x(x + 6) minus 2(x + 6), (x + 6)(x + 2).
In which step did Mia make an error?
Step 1
Step 2
Step 3
Step 4
Mia's error is in step 4
What is factorization?Factorization involves splitting a function into several factors
The steps in factorizing the expressions are:
Step 1: x^2 + 6x - 2x -12
Step 2: (x^2 + 6x) - (2x + 12)
Step 3: x(x + 6) - 2(x + 6)
Step 4: (x + 6)(x + 2)
From the step 3 to step 4, the resulting expression should be
(x + 6)(x - 2)
However, the step 4 of the expression is (x + 6)(x + 2)
The expected expression and the actual expression in step 4 are different.
Hence, Mia's error is in step 4

x= ?
Answer:
X = 2√41
Step-by-step explanation:
Uaing the pothagorean therom, (a squared plus b squared equals c squared) find the square of both 8 and 10 which are
8 squared - 64
10 squared - 100
Add them together to get
164
√164 = x
You can reduce that to 2√41
Solve the system of equations
Y = 2x
X - Y = 10
Answer:
x=-10, y=-20
Step-by-step explanation:
first you substiture the y in the second equation with the first
x-2x=10
then solve
1x-2x=-1
-x=10
multiply both sides by a negative to make the varible a
positive
x=-10
now we substitue the x in the first equation with -10
y=2(-10)
y=-20
evaluate each expression when x=3 (iready)
Answer:
3
Step-by-step explanation:
x^5 = ?^5
x = 3
We plug in x = 3:
3^5 = ?^5
We find the fifth root of both sides and get:
3 = ?
That means that 3 is the answer
Answer:
3
Step-by-step explanation:
To evaluate the expression you would add in the x so in BLANK^3
you would plug in the x which is 3.

Fill in the blank so that the ratios are equivalent. 3:9 and 6:
Answer: 18
Step-by-step explanation: The ratio 3:9 is equivalent to 1:3. This means that whatever number on the left side of the ratio should be multiplied by 3 to get the one on the right. 6 x 3 = 18.
The value of the unknown number for the fraction is equal to 18.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio is 3:9 then the value of the unknown number will be calculated as,
The ratio 3:9 is equivalent to 1:3. This means that whatever number is on the left side of the ratio should be multiplied by 3 to get the one on the right.
The unknown number will be,
6 x 3 = 18.

What’s the value of a?
Answer:
a = 69
Step-by-step explanation:
The linear pair equals 180 degrees.
a + 90 + 21 = 180
a + 111 = 180
a = 69
nice!
Answer:
A= 69 degrees
Step-by-step explanation:
if all those angles equal a total of 180 degrees then all you need to do is add the angles your given which in this case is 21 and a 90 degree angle which would equal 111 degrees, then subtract 111 from 180 and that would be the answer to the missing angle, which is 69 degrees.
21 + 90 = 111
180- 111 = 69
