-x^2 - 5x - 4 = -x^2 + 9x - 18
-5x - 9x = -18 + 4
-14x = -14
x = -14/-14
x = 1 <====
y = -x^2 - 5x - 4
y = (-1^2) - 5(1) - 4
y = 1 - 5 - 4
y = 1 - 9
y = -8 <====
Answer:
m<D = 26
Step-by-step explanation:
Exterior angles thm:
83 + 6x - 4 = 21x + 4
6x + 79 = 21x + 4
6x - 21x = 4 - 79
-15x = -75
x = 5
m<D:
6x - 4
6(5) - 4
30 - 4
26
Is it number15?
then it is
3x = 180
x = 60
x will be 60
Answer:
5.) 39
6.) 52
Step-by-step explanation:
5.) 90-51= 39
6.) 74 + 34= 108
180-108= 72
56+72= 128
180-128= 52
x=52
