Create an equation using the formula for area of a rectangle; area = width * length
(X + 2)(x + 3) = 600
Multiply the dimensions.
X^2 + 3x + 2x +6 = 600, or simplified x^2 +5x + 6 = 600.
Subtract 600 to get the following:
X^2 + 5x - 594 = 0
Factor by x:
(X - 22)(x + 27) = 0
Solve for x
X - 22 = 0
X = 22.
Use the POSITIVE VALUE of x as you can’t have a negative area for a room.
Then substitute 22 for x to get the dimensions
(22+ 2) or 24 for length and (22+3) or 25 for width.

Answer:
True
Step-by-step explanation:
In scalar multiplication, each component of the vector is multiplied by the scalar. The description is True.
Step-by-step explanation:
x+9-10=500
x-1=500
x=500+1=501
Answer:
x = 6
Step-by-step explanation:
When 2 chords of a circle intersect then the product of the parts of one is equal to the product of the parts of the other, that is
2x = 3 × 4, that is
2x = 12 ( divide both sides by 2 )
x = 6
Answer:
3.75
Step-by-step explanation:
5 1/4÷1/3
so,
= 5 1/4×3/1
= 5 × 0.75
= 3.75
