I'm thinking it MIGHT be -21 but I'm not sure.
Answer:
x=5
Step-by-step explanation:
since two sides are congruent, the two unknown angles are congruent.
All triangle angles total 180 degrees.
so:
180-88=92
92/2=46
9x+1=46
9x=45
x=5
Answer:
10b=120
Step-by-step explanation:
b=12
The answer is -12
Since -12 < 0 = no solutions
Discriminant Formula: b^2 - 4ac
b^2 - 4ac > 0 2 solutions
b^2 - 4ac = 0 1 solution
b^2 - 4ac < 0 no solutions
x^2 - 6x + 12 = 0
a = 1
b = -6
c = 12
-6^2 - 4 (1) (12)
36 - 48
= -12
-12 < 0 = no solution
160 = 2 x 2 x 2 x 2 x 2 x 5 = 2^5 x 5
243 = 3 x 3 x 3 x 3 x 3 = 3^5
So
(160 * 243)^1/5
= 5th root of (160 * 243)
= 5th root of (2^5 * 5 * 3^5)
= 2 * 3 * (5th root of 5)
= 6 * (5th root of 5)
Answer is D. 6 * (5th root of 5)
