Hello!
Recall that:
is equal to . Therefore:
There is also an exponent of '6' outside. According to exponential properties, when an exponent is within an exponent, you multiply them together. Therefore:
Answer:
1) 8
2) 9
3) 8
4) 12
Step-by-step explanation:
Well, assuming the sides that are numbered are the same length (not sure because no instructions). You have to do is set both equal to each other. An example being:
6 = 2x - 10
16 = 2x
8 = x
And you just do that with the first three problems.
For number 4 set them equal to each other, solve for x and then plug x back into the equation.
2x - 6 = x + 3
x = 9
2(9) - 6 = 18 - 6 = 12
And for number 5 set them equal to each other, solve for x, then plug in x like the previous problem and that's the answer because they are all 90 degree angles.
Answer:
8 pounds per week
Step-by-step explanation:
AVG= total/time span
so
AVG= 128/16
AVG= 8 pounds per week
Hope this helps!
