A because it can be rearranged to the y = mx + c format. y = -1/40 x + 4
Answer:
Step-by-step explanation:
Given
← factor the numerator and denominator
= 
← cancel (x + 4 ) on numerator/ denominator
=
First way of finding area is the usual formula.
Area of a rectangle = Length × Breadth
= 3x × x
= 3x^2
Second way of finding area of the bigger rectangle is adding both the rectangles' areas and subtracting by the area of the smaller rectangle.
Area of smaller rectangle:
Length × Breadth = 2 × x
= 2x
Area of bigger rectangle + Area of smaller rectangle = 3x^2 + 2x
Subtracting it by the area of the smaller rectangle:
3x^2 + 2x - 2x = 3x^2
Answer:
0.8
Step-by-step explanation:
The original answer is 0.8125. The tenths place is the number right after the decimal. From here, you determine whether the next number (after the 8) follows the "5 or greater" rounding rules and round to the nearest tenth from there.
