Solutions will be unreal

Step-by-step explanation:

Given the quadratic equation ax^2+bx+c

The discriminant of the function determines its nature of its root

Discriminant D = b^2-4ac

If D <0, it shows that the roots of the equation will be a complex value. since D is less than 0 and the square root of a negative number does not exist. Hence, the solutions will be unreal

If ABC = DEC,<br> B= 44º and E= 4x<br> x= [?]
kolezko [41]

Value of x is 11

Step-by-step explanation:

  • Step 1: Find x when ΔABC ≅ ΔDEC.

When these two triangles are congruent, their corresponding angles and sides will be equal.

⇒ ∠B = ∠E

⇒ 44° = 4x

∴ x = 44/4 = 11

AfilCa [17]
Given a variable, x, the compound ineaquality representing the range from a to b inclusive of the variable is given by

a\leqx\leqb
where a is the least value and b is the greatest value.

Thus, given a variable f, representing the frequencies for the three octaves of a <span>typical acoustic guitar.
</span>
Where the range of the frequencies is between 82.4 Hertz and 659.2 Hertz inclusive.

The complex inequality, representing <span>the range of frequencies for a guitar tuned to "concert pitch"</span> is given by

82.4\leq f\leq659.2
