This uses the Pythagorean Theorem, which is a^2 + b^2 = c^2 . All you need to do is switch that formula around and you can get the answer easily.
10^2 + b^2 = 16^2
100 + b^2 = 256
b^2 = 156
b= 12.489, or 12.49 rounded
-2.4m>-6.8m.negative numbers are always are always more positive the lesws numerically they are. However 3 cannot be an answer. unless it is greater than 3.
Remember that when multiplying fractions, we multiply everything on the top and everything on the bottom.
a * b * c
(-2 / 5) * (20 / 32) * (-4 / 10)
(-2 * 20 * -4) / (5 * 32 * 10)
160 / 1600
1 / 10
Correct answer: D. 1/10
Hope this helps!! :)
Isolate the variable by dividing each side by factors that don't contain the variable.
