The area of 4 and 9 is 36 because you multiply the width and length
Answer:
Step-by-step explanation:
It can be any, exept right, because the scalene, obtuse, and isosceles, they can all have an acute angle in it some where.
So, for isosceles, you have that really tiny little point. So, only the first three answers are correct. :D
When solving for this problem, replace x with the first coordinate and solve. if the answer is what you have for the second, it is correct. The first number in an ordered pair is your x and the second is your y. So I would rewrite the equation like this and solve.
y=7x-19 y=7x+21
2=7(3)-19 9=7(4)-19 2=7(3)+21 9=7(4)+21
2=21-19 9=28-19 2=21+21 9=28+21
2=2 9=9 2=42 9=49
as you can see it is the first equation.
25% is equal to 1/4. If 3 bars is 1/4 of a box, then there are 3*4 = 12 bars in a box.
