Answer:
180
Step-by-step explanation:
Area of troiangle=180
A+B+C=180
22+90+B=90
112+B=180
B=180-112
B=68
perimeter=A+B+C
22+90+68=180
Answer:
14 + 25l + 6l^2
Step-by-step explanation:
(7 + 2i) (2 + 3i)
=> 14 + 4l + 21l + 6l^2
=> 14 + 25l + 6l^2
This is the correct answer
Step-by-step explanation:
We need to write the function that have two real number zeros by calculating the discriminant i.e. .
We know that,
If D>0 the roots are real and unequal
If D= 0 roots are real and equal
If D< 0 roots are imaginary or not real and unequal
Function (1)
D>0 the roots are real and unequal
Function (2)
D<0 the roots are real and unequal
Function (3)
D>0 the roots are real and unequal
Function (4)
D>0 the roots are real and unequal
Function (5)
D<0 the roots are real and unequal
Function (6)
D>0 the roots are real and unequal
(1),(3),(4) and (6) have two real number zeroes.
If you would like to calculate - 5 * g - 6 for g = -2, you can do this using the following steps:
- 5 * g - 6 = - 5 * (- 2) - 6 = 10 - 6 = 4
g = -2
The correct result would be A. 4.
Hi there are 16 students said meaning there 4 left of the 20. So maybe the remaining students take both. That would be 4/20 simplified to 1/5.
