Find the value of Z.<br> A)7<br> B)9<br> C)11<br> D)12
Gala2k [10]
As per the isosceles triangle theorem, if the two base angles are congruent then the legs are also congruent, so we must set the two legs equal to each other:

2z - 15 = 9

Add 15 to both sides:

15 - 15 = 0
15 + 9 = 24

Divide 2 from each side:

2z = 24

2z/2 = z

24/2 = 12

z = 12

Hence, the answer would be D: z = 12

PLEASE HELP! Find code (answer)
alexandr1967 [171]

Answer:

code = 56

Step-by-step explanation:

E = GCF(22,30) = 2

F = LCM(3,8) = 24

Given

3 * (7+10) = G +30 => 51 = G + 30 => G = 21

5 * (3+H) = 15 + 45 => 3+H = (60/5)  = 12 => H = 12 - 3 = 9

Sum E + F + G + H = 2 + 24 + 21 + 9 = 56

Anderson uses the discriminant to correctly find the number of real solutions of the quadratic equation one-halfx2 + 4x + 8 = 0.
Kazeer [188]

Answer:

No real roots.

Step-by-step explanation:

Discriminant = b^2 - 4ac      ( for the equation ax^2 + bx + c = 0)

Here it is  4^2 - 4*1*8

= `6 - 32

= -16.

This is negative so there are no real roots.
