Answer:

m < 49/12

Step-by-step explanation:

The portion of the quadratic formula under the square root sign is the discriminant.

If the discriminant is > 0 then there are two real roots.

b² -4ac > 0

-----------------------------

7² - 4(3)m > 0

49 - 12m > 0

Subtract 49 from both sides

-12m > -49

Divide both sides by -12

(when multiplying or dividing by a negative the inequality must be reversed)

m < 49/12

Help me on isosceles and equilateral triangles problems. Find the value of x in the triangle shown below.​
trapecia [35]

Answer:

  x° = 61°

Step-by-step explanation:

Both of the "unknown" angles in the triangle are equal, since their opposite sides have equal lengths. (The triangle is isosceles.) The sum of angles in a triangle is 180°, so we have ...

  58° + x° + x° = 180°

  2x° = 122° . . . . subtract 58°, collect terms

  x° = 61° . . . . . . . divide by 2

Claire made 1⁄2 pound of trail mix. If she puts 1⁄4 pound of trail mix into each bag, how many bags are filled?
aleksklad [387]
Claire would have filled two bags.
1/2 (or .5) ÷ 1/4 (or .25) = 2

Since both units are in pounds, you don't need to convert anything.
