Answer:
x+3 will be factor of polynomial
Step-by-step explanation:
We have given polynomial
We have to find that is x+3 is one of factor of polynomial
For this if x+3 will factor of polynomial
Then if we put x=-3 in the polynomial then the the value of polynomial will be zero
As
So x+3 will be factor of polynomial
Answer:
Perimeter of ABCD - Perimeter of PQRS = 4x + 2
Step-by-step explanation:
i. For rectangle ABCD;
length, l = 2x -3
width, w = 4x + 5
Perimeter of a rectangle = 2(l + w)
Perimeter of ABCD = 2((2x -3) + (4x + 5))
= 2(2x -3 + 4x + 5)
= 2(6x + 2)
Perimeter of ABCD = 12x + 4
ii. For rectangle PQRS;
length, l = x - 1
width, w = 3x + 2
Perimeter of a rectangle = 2(l + w)
Perimeter of PQRS = 2((x - 1) + (3x + 2))
= 2(x - 1 + 3x + 2)
= 2(4x + 1)
Perimeter of PQRS = 8x + 2
So that,
Perimeter of ABCD - Perimeter of PQRS = (12x + 4) - (8x + 2)
= 12x + 4 - 8x - 2
= 4x + 2
Perimeter of ABCD - Perimeter of PQRS = 4x + 2
The no. is 8.
31 - 7 = 24
3 x 8 = 24
B + (-60) = -14
-60 -60
---------------
b = -74
What error, if any, did Maureen make?
Maureen's work is correct, and her original balance was -$74.
Maureen should have added 60 to both sides.
Maureen should have added 14 to both sides.
Maureen made a computational error when she subtracted -14 - 60
