Answer:
3x³+10x²-8x-2
Step-by-step explanation:
(-3x³+7x²-8x+11)-(-3x²+13)
- remove unnecessary parentheses
-3x³+7x²-8x+11-(-3x²+13)
-3x³+10x²-8x+11-13
-3x³+10x²-8x-2
Answer:
L=21.6in and w=13.6
Step-by-step explanation:
If the length is 8 inches longer than its width, we can write the width as "w" and the length as the width w+ 8
Area is (width)(Length) = (width)(width+8)
W
----------

| | L = w+8

-----------
A = (w+8)(w)
A = w2 + 8w = 295.
(Problem states that area is 295 sq in)
Need to solve this quadratic equation
w2 +8y - 295 = 0
Factor:
(w - 13.64) (w + 21.64) = 0
So
w - 13.64 = 0. or. w + 21.64= 0
Solve these and get
w = 13.64. or. w = -21.64
Only one that makes sense in real life is the poitive one.
So the dimensions are
Width = 13.64 inches
Length = 21.64 inches
Answer:
(1, - 3 )
Step-by-step explanation:
Using the translation rule (x, y ) → (x + 2, y + 1 ), then
B(- 1, 2 ) → (- 1 + 2, 2 + 1) → (1, 3 )
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
(1, 3 ) → (1, - 3 )
Answer:
When the Supreme Court rules on a constitutional issue, that judgment is virtually final; its decisions can be altered only by the rarely used procedure of constitutional amendment or by a new ruling of the Court. However, when the Court interprets a statute, new legislative action can be taken.
