Answer:
choice 4) SAS
Step-by-step explanation:
To find (f+g)(x), add the equations and simplify by combining like terms.
(x/2)-2+2x^2+x-3
2x^2+ (x/2) +x -5
2x^2 + (1/2)x+x -5
2x^2+ (3/2)x -5
Final answer: C
Remember that (x/2) is the same as (1/2)x. They both represent half of x.
Area of the shaded region = 80 in²
Explanation:
The outer diagram is a square
Area of the square = length × length
length = 12in
Area of the square = 12in × 12in
Area of the square = 144in²
There are 3 smaller squares in each row and column:
The length in each row and colum = 12
the length o fone small box = 12/3 = 4
Area of the smaller box = 4in × 4in = 16 in²
There are 4 boxes unshaded
Area of 4 unshaded boxes = 4 × 16 in² = 64in²
Area of the shaded region = Area of the outer box - area of the unshaded boxes
Area of the shaded region = 144 - 64
Area of the shaded region = 80 in²
