The correct answer is (x+2)(x-9) here are the steps :)
The middle number is -7 and the last number is -18z
Factoring means we want something like
(X+_) (X+_)
Which number go in the blanks?
We need two number that
•Add together to get -7
•Multiply to get -18
Can you think of the two numbers?
Try 2 and -9:
•2+-9=-7
•2*-9=-18
Fill the blanks in
And you get
(X+2)(x-9)
Hope this helps :)
Answer:
Therefore we come to a conclusion that,
Gregory's Rectangle is in Area.
Step-by-step explanation:
Given:
Fiona draws a 24 centimeter rectangle.
Gregory draws a 24 square inch rectangle.
To Find:
Whose rectangle is in area = ?
Solution:
Rectangle has a dimension as
Length and Width which are in meters, centimeters, inches, feet, units, etc.
For Area
here units are getting Multiplied so it becomes
unit × unit = unit² = square units
m × m = m² =square meter
inch × inch = inch² =square inches
Hence Area is calculated in square units.
Therefore we come to a conclusion that,
Gregory's Rectangle is in Area.

Step-by-step explanation:
Answer:
x = -3 + 2 i or x = -3 - 2 i
Step-by-step explanation:
Solve for x:
x^2 + 6 x + 13 = 0
Hint: | Solve the quadratic equation by completing the square.
Subtract 13 from both sides:
x^2 + 6 x = -13
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 9 to both sides:
x^2 + 6 x + 9 = -4
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x + 3)^2 = -4
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x + 3 = 2 i or x + 3 = -2 i
Hint: | Look at the first equation: Solve for x.
Subtract 3 from both sides:
x = -3 + 2 i or x + 3 = -2 i
Hint: | Look at the second equation: Solve for x.
Subtract 3 from both sides:
Answer: x = -3 + 2 i or x = -3 - 2 i
