Answer:
Step-by-step explanation:
The student hasn't finished the factoring yet.
<u>He still needs the step:</u>
<u>The next step:</u>
- 0 = 2x + 5, 0 = x + 1
- x = - 2.5, x = - 1
Just like you drew those dotted lines. You know how to find the areas of rectangles which is A=length x width
The answer would be 20cm^2+6cm^2+18cm^2=44 cm^2
If P has Cartesian coordinates (7, pi/3), then its Polar coordinates are (square root of ((7)^2 + (pi/3)^2) , arcton (pi/21))
<u>Explanation</u>:
The given coordinates (
7
, π
/3
) look as if they are already in polar form (radius = 7
, and angle = π/3).
but in case (
7
, π
/3
) really are Cartesian coordinates (i.e. (
x
,
y
) =
(
7
, π/3
)
)
The radius is given by √(
x /2 + y/
2) and the angle by the arctan (
y
,x
).
Answer:
The correct answer is 11x² + 11x - 6
Step-by-step explanation:
The given expression is,
(4x² + 12x - 9) + (7x² - x + 3)
<u>Simplify the given expression</u>
(4x² + 12x - 9) + (7x² - x + 3) = 4x² + 12x - 9 + 7x² - x + 3
= 4x² + 7x² + 12x - x - 9 + 3
= 11x² + 11x - 6
Therefore the simplified form of given expression is 11x² + 11x - 6
