when asked to factor the x^2 - 100, a student gives the answer (x -10) (x-10). what is wrong with this answer?
aalyn [17]

x^2-100\\\\=x^2-10^2\\\\=(x+10)(x-10)\\\\\text{The difference of two  squares formula is}~ a^2 -b^2 =(a+b)(a-b),\\\\\text{So, the student did not apply it properly}

Answer:

3.56*10^13

Step-by-step explanation:

8.9* 10^4  * 4*10^8

Multiply the number out front and then the exponents

8.9 * 4  * 10^4 * 10^8

When we multiply powers when the bases are the same, we add the exponents

35.6 * 10^(4+8)

35.6 *10^12

But this is not in proper scientific notation.  Only one digit before the decimal

Move the decimal one place to the left, that means we need to add 1 to the exponent

3.56 *10^(12+1)

3.56 * 10^13

Find the value of x and y <br>&lt;1=(10x) <br>&lt;2=(10y+20)<br>&lt;3 =100 ​
Rufina [12.5K]

Answer:

  1. 100
  2. 80
  3. 100
  4. 80

x = 10

y = 6

Step-by-step explanation:

We can use the vertical angle theorem to solve for most of this problem. We know that 1/3 will have the same measure and so will 4/2. We can create an equation to solve for 1 and 3.

10x = 100

x = 10

We aren't given angle 4 so we are going to have to solve that ourselves. We can create an equation knowing that 4 and 3 will create a supplementary angle.

100 + z = 180

z = 80

Now, that we have angle 4, we know that angle 2 will have the same measure because they are vertical angles. Now to find the value of y, we can take the angle measure and solve for it.

10y + 20 = 80

10y = 60

y = 6

Best of Luck!
