(0, -1) (2,4)
4 - -1/ 2 - 0
5/2
The answer will be D
Answer:
Step-by-step explanation:
hello :
- 2u + 12u ² + 8 - u ^ 9 = -1u ^ 9+12u² -2u+8...standard form
the degree is 9 and leading coefficient is -1
D=2r=2·4=8 cm
A = L² (L=d)
A = 8² = 64 cm²
The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
