Answer:
Step-by-step explanation:
43 square units. Since each square is equal to one square unit, all you have to do is count the amount of squares inside the given polygon. Double check it if you want. You could also calculate the areas of the main rectangle and the little thing coming out at the top right separately and then add them together.
Question
x+5/x+2 - x+1/x²+2x
Answer:
= (x² - 4x - 1)/[x (x+2)]
= (x² - 4x - 1)/[x² + 2x]
Step-by-step explanation:
x + 5/x + 2 - x + 1/x² + 2x
We factorise the second denominator to give us :
x + 5/x + 2 - x + 1/x(x + 2)
We find the L.C.M of both denominators which is x(x+2).
[x(x + 5)-(x + 1)] / (x (x + 2))
Expand the bracket
=[x² +5x - x -1] / [x (x + 2)]
=(x² - 4x - 1) / [x (x + 2)]
= (x² - 4x - 1)/ [x (x + 2)]
= (x² - 4x - 1) / [x² + 2x]
Your answer:
<span>Equation:
x(x+1) = 2(x+1)+77
-----
x^2+x = 2x+79
x^2-x-79 = 0
------
This quadratic does not have an integer solution.</span>

f(8)=2.8+5=21
g(8)=3.8+6=30
f-g(8)=21-30= -9
Answer:
The errors are;
a. negative 4 to negative 6
b. negative 2 to negative 4
Step-by-step explanation:
The number line is the mathematical representation of numbers in the horizontal line or the x-axis.
The result of the multiplication of a positive 2 and a negative 3 is;
2 x -3 = -6 , gives a negative 6.
So the number line should scale to accommodate the operands and the result, which is from negative 7 to positive 3, in the option given.
