Answer:
there are 2 solutions in total
Step-by-step explanation:
x^2-4=0
x^2=4
x= ±2<em>i</em>
Answer:
A) -1
Step-by-step explanation:
anything raised to the zero power is 1 but if there is a negative without parentheses around it then it becomes -1
ex, (-4)° = 1
Answer: 69
Step-by-step explanation:
If popcorn is p and water is w the equation can be written as
3p + w = 9.25
because there was 3 boxes of popcorn and one water (hence the coefficients) and the total is 9.25
then plug in 1.75 for w the price of water:
3p+ 1.75 = 9.25
you can move stuff around algebraically now (subtract 1.75 on both sides and divide by three on both aides) to get the cost of one box of popcorn (p).
The answer is 2.50
Answer:
I only know the answer to B which is 50*
Step-by-step explanation:
B is 50* because there are 3 vertical lines therefore the angle opposite of 80* is also 80* so when we add them together, we can take 160* out of the 360* whole. so now we are left with 200* which are 2 sets of vertical lines and one of each of the vertical lines are x therefore the remaining angles are equal so all I have to do is divided 200* by 4 which is 50 therefore x is equal to 50*.
PS: the * sign is supposed to be the degree sign but I don't have it on the keyboard so just act as if it was the degree sign lol
