Can someone help me out

Firstly, you want to multiply (f^4)^2. \frac{2*f^8*f^2}{8f^{12}}


Next, multiply everything on the numerator. \frac{2f^{10}}{8f^{12}}


Next, divide. \frac{2f^{10}}{8f^{12}}=\frac{1}{4} f^{-2}


Now remember that f^-2 = (1/f^2), so just convert the negative powered exponent to that, and your answer will be \frac{1}{4f^2}

Find the two-digit number which is 2 times the sum of its digits. Find a statement and number, please.
poizon [28]
A two-digit number is twice the sum of its digit. If the tens digit is 7 less than the unit digit, find the number. 
Let x= the unit digit
Then y= the tens digit
<span>And 10y+x= the number 


</span>x+y= the sum of the digits 
<span>Now we are told that 10y+x=2(x+y) ------1st equation </span>
<span>We are also told that y=x-7 ----------- 2nd Equation </span>
<span>So our equations to solve are: </span>
(1) 10y+x=2(x+y)
<span>(2) y=x-7 
</span>

Hope it helps

Help asap pls and thx

Step-by-step explanation:

from what I can see there are 2 options to make the 2 triangles congruent :

either the opposite sides must be equal or the neighboring sides must be equal.

so, either

5x = 3x + 10

and

5x - 2 = 4x + 3

or

5x = 4x + 3

and

5x - 2 = 3x + 10

for the first

5x = 3x + 10

2x = 10

x = 5

control

5x - 2 = 4w + 3

5×5 - 2 = 4×5 + 3

23 = 23

correct.

for the second

5x = 4x + 3

x = 3

control

5×3 - 2 = 3×3 + 10

15 - 2 = 9 + 10

13 = 19

no, not a valid solution.

so, x = 5
