If you would like to solve 16x^2 - 81 = 0, you can calculate this using the following steps:
<span>16x^2 - 81 = 0
</span>(4x - 9) * (4x + 9) = 0
1. 4x - 9 = 0 ... 4x = 9 ... x = 9/4
2. 4x + 9 = 0 ... 4x = - 9 ... x = - 9/4
The correct result would be: <span>x = 9 over 4, x = −9 over 4.</span>
Answer: 4 UNITS LEFT!!!
Step-by-step explanation: I know it!
Please give me brainiest
Hope I helped :)
The square of a binomial expands as follows:
Expanding all the binomials, we have
Sum like terms:
Simplify terms appearing on both sides:
Move all terms involving k to the left and all numbers to the right:
Divide both sides by -20:
bus A takes 25 mins
bus B takes 35 mins
start at 8am
to find =lcm of 25 and 35
LCM of 25 and 35
5 /__25,35
/__5,7
LCM=5×5×7
=175 mins=8hr+175mins=10:55am
The solution is undefined, the function is parallel. Also the two functions are lunar functions, mx+b=y.
M= slope
B=y-intercept (where it crosses the y-axis)
