The answer is 20. you'll have to multiply 10 times 3 and get 30. Then you'll subtract the 10 from the 30 and get 20
Step-by-step explanation:
4/sin45=

It may be easier to start from
.. a(x +3)(x -1) = 0
.. a(x^2 +2x -3) = 0
The quadratic
.. ax^2 +bx +c = 0 will have solutions -3 and 1 for ...
.. a ≠ 0
.. b = 2a
.. c = -3a
Answer:
29
Step-by-step explanation:
Use PEMDAS
5^2 + 8 ÷ 2
25 + 8 ÷ 2
25 + 4
