We have the following expression:
9 ^ n = 49
We apply logarithm to both sides of the expression:
log9 (9 ^ n) = log9 (49)
By properties of logarithm we have:
n = log9 (49)
n = 1.771243749
round to the nearest ten thousandth:
n = 1.7712
Answer:
n = 1.7712
The top one is 30. 8*2=16. 12*2=24 then add them together. which is 30. I don't know the last one.
12x + 5 - 4x + 2x² =
= 2x² + 12x - 4x + 5 = <u>2x²</u><u> </u><u>+</u><u> </u><u>8x</u><u> </u><u>+</u><u> </u><u>5</u>
You will solve this by converting the x and y axis and then dividing by 2 then you will add 5
