Answer:
(2x + 7)(x + 3)
Step-by-step explanation:
2x² + 13x + 21
2x² + 6x + 7x + 21
2x(x + 3) +7(x + 3)
(2x + 7)(x + 3)
Answer:
32
Step-by-step explanation:
Given
-x (y + z)
If y = -3
x = 4 and
z = -5
Substitute the respective values into the expression
-(4) (-3 + -5)
Positive negative when combined gives negative
-4 ( -3 - 5)
Simplify the bracket
-4 (-8)
-4 x -8
Negative negative gives positive
32
Let the medium angle be B degrees
the small angle be A degrees
the large angle be C degrees
Then
C = 2 B + 20 ..................X
5 B = A + C ..................Y
Sum of all angles
A + B + C = 180 .............Z
Applying Y in Z
5 B + B = 180
6 B = 180
B = 30
From X C = 2 x 30 + 20 = 60 + 20 = 80
From Y 5 x 30 = A + 80
150 = A + 80
150 - 80 = A = 70
Hence medium angle B = 30 degrees
the small angle A = 70 degrees
the large angle C = 80 degrees
