Answer:
d
Step-by-step explanation:
3/5 is equal to .6. however it can be simplified from 6/10, 9/15, etc
but 4/6 cannot be simplified to 2/5
(3 + 6i)(3 + 7i)
FOIL: First, Outside, Inside, and Last
3 x 3 = 9
3 x 7i = 21i
6i x 3 = 18i
6i x 71= 42i
9 + 21I + 18I + 42I = 9 + 81I
a = 9
B = 81I
Answer:
±1, ±2, and ±4
Step-by-step explanation:
4x² + bx + c = (Ax + B) (Cx + D)
Distribute:
4x² + bx + c = ACx² + (AD + BC) x + BD
Matching the coefficients, AC = 4. So A must be a factor of 4. Possible values of A are therefore ±1, ±2, and ±4.

Answer:
The answer is in the explaination
Step-by-step explanation:
A + B = 180 degrees
14x - 72 = 180
14x = 108
x = 8
A = 5 times 8 plus 20
A = 60
