Answer:
96
Step-by-step explanation:
= 2(b+c)2-3(b-c)
= 2(8+4)2-3(8-4)
= 2(8+4)1(8-4)
= 2×12×1×4
= 96 ans
Answer:
False
Step-by-step explanation:
Answer:
75
Step-by-step explanation:
If the figure is a pentagon with 5 sides, then the angles must add to 540.
120 + 120 + 2x + x + x = 540.
Solve by combining like terms and subtracting them from 540.
240 + 4x = 540
4x = 300
x = 75
For 5x-2y=-6 it is 2.5x+3 and for 15x-6y=-6 is 2.5x-1
