Yes so for example starting at number 10 (x to the second power = 49) x would equal 7 because 7 to the second power is 49. (7x7= 49) Your answer is x=7.
Number 2 is x = 10 because 10 x 10 = 100
B is the answer due to 180-250
Answer:
I am asssuming you are trying to find something like (x-2)(x+3) but this wouldnt be possible just give the actual original question
Step-by-step explanation:
Let’s remember the most basic thing in percentages, the equation.
Percent x Whole = Part.
We know the whole, and the part, but we are trying to find the percent, so we have to divide the two, first turn your whole and part into a decimal.
Percent x 0.4 = 0.18, so we divide 0.18 by 0.4
0.18/0.4 = 0.45
0.45 = 45%
Scale factors of negative numbers are contractions
scale factors of numbers greater then 1 are expansions
scale factors of numbers greater then 0 but less then 1 are contractions
