Answer:
$28.68
Step-by-step explanation:
57.24+64.08
121.32
150-121.32
Área of rectangle= 18 x 14 = 252
Area or triangle=
30-18= 12
12 is the base of the triangle
14 is the height of the triangle
Area of a Triangle= 1/2bh
1/2(12)(14)=84
Área of Triangle= 84
252+84= 336
Answer= 336
Answer:
1 turn
Step-by-step explanation:
this is what the graph would look like:
3 + 1.75m
This represents 1.75 per mile plus a one time 3 charge.
Another way this can be written is
(1.75m + 6) - 3
This is a less efficient way, but represents the same. It is 1.75 per mile, this is plus 6, therefore we add the -3 outside the parenthesis so it evens out to +3 as the base charge.
Example: Lets say its 3 miles.
3 + 1.75 (3) = 8.25
(1.75 (3) + 6) - 3 = 8.25
Answer:
The correct option is;
B. This equation is not considered to be a quadratic equation because it is not in the form a·x² + b·x + c = 0
Step-by-step explanation:
A. The given equation, x² - c = 0, can be presented in the form of the difference of two squares as follows;
(x + √c)·(x - √c) = 0
B. The equation x² - c = 0, is a quadratic equation because it is a polynomial equation of degree 2
C. The equation x² - c = 0 can always be factored as (x + √c)·(x - √c) = 0
D. Where c > 0, the equation x² - c = 0 can by the square root property as follows;
x² - c = 0
x² = c
x = √c
