Answer:
I think the answer is 11. 18
Answer:
Answer is B
Step-by-step explanation:
Area of Square = Base*Height
Base=(x+1) Height=(x+1)
Therefore Area=(x+1)(x+1) or (x+1)^2
By expanding the brackets e.g. x*x is x^2 then x*1 is x and so on you get:
x^2+x+x+1 this simplfies to x^2+2x+1
Area = x^2=2x+1
Unless they have given you a value for x, this is the equation for the area of said square.
Number 7 is 16 and #6 is 29
and 8 is 45
Answer:
A = 3x³ - 22x² + 30x - 36
Step-by-step explanation:
Area of a Rectangle: A = lw
Step 1: Define
l = 3x² - 4x + 6
w = x - 6
Step 2: Substitute and Evaluate
A = (3x² - 4x + 6)(x - 6)
A = 3x³ - 4x² + 6x - 18x² + 24x - 36
A = 3x³ - 22x² + 30x - 36
