Choosing the product of power property,when you multiply exponentials with the same base , you add their exponents.
This is represented as :
This property is true in that ;
where you have x³ × x³ , x³ is x*x*x and the other x³ is x*x*x .Adding the xs will give x⁶ which is similar to 3+3=6 xs

Step-by-step explanation:
2x-3y=11
3x+3y=9
do addition and you should get
5x=20
x=4
plug in x into any equation
12+3y=9
3y= -3
y=-1

Answer:
5/16 as a decimal is 0.3125.
Answer:
Step-by-step explanation:
45 = (b(4b - 2))/2
90 = 4b2 - 2b
4b2 - 2b - 90 = 0
(2b + 9)(2b - 10) = 0
2b + 9 = 0
2b = -9
b = -9/2
If we were looking for zeroes, this would be an answer, but since we're looking for measurement, we don't use negative numbers.
90 = 4b2 - 2b
4b2 - 2b - 90 = 0
(2b + 9)(2b - 10) = 0
2b + 9 = 0
2b = -9
b = -9/2
