I wrote it out on paper and uploaded the answer for you. Let me know if you have any questions.
You have to do 7 x 4 because a square has four sides
Answer:
sometimes
Step-by-step explanation:
If this is an "always, sometimes, never" kind of problem, the answer is sometimes.
An isosceles triangle can be an obtuse triangle sometimes (but might be right or acute. An obtuse triangle can be isosceles or may be scalene. An obtuse triangle cannot be a right triangle nor equilateral.
The names for triangles comes from their angles:
right, acute, obtuse;
OR from their sides:
scalene, isosceles, equilateral.
3 x 3 - ( (-1)^2 - 2)^2
Start evaluating the one in the most inner bracket:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1 - 2)^2
There is one more bracket, so we do what is in the bracket:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1- 2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
Between x and -, we do the x first:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1- 2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
= 9 - 1
Then we do the -:
3 x 3 - ( (-1)^2 - 2)^2
= 3 x 3 - (1- 2)^2
= 3 x 3 - (-1)^2
= 3 x 3 - 1
= 9 - 1
= 8
The value of the 9 in 0.792 is 0.090. Because it is asking you what the value of that singular number is, you have to get rid of all the other numbers besides the 9. Then you are left with 0.090. Hope this helps!
