The factors, (9x - 4) and (9x +4), are obtained from factoring the sums of two square. Their product is obtained by subtracting the square of the second term from the square of the first term.
(9x)² - (4)² = 81x² - 16
The values of a and b are 81 and 16, respectively. Therefore, the answer is 81.
Answer:
a) at x=0.5 y=2 and at x=1 y=2 this similarity in values shows that the solution for x is between 0.5 and 1
c) The x solution will be between x=0.0 and x=0.7 .
There is a similarity in values of y at x=0.6, y=2.4 and at x=0.7 , y=2.4
d) For x= (0.6+0.7)/2 = 1.3/2 =0.65
For y= (2.4+2.3)/2 =4.7/2=2.35
Approximate solution is (0.65, 2.35)
Answer:
- No triangle possible
- Triangle possible
- No triangle possible
- No triangle possible
Step-by-step explanation: The lengths of any two sides of a triangle must add up to more than the length of the third side (Triangle Inequality Theorem). The sum of the interior angles add up to 180°.
The shaded area's Fraction= 21/100 and Decimal = 0.21.
<u>Step-by-step explanation:</u>
When an area is divided into multiple smaller regions ( smaller squares ) is called parts.
In case of Squares, it can be divided into either rows or columns, sometimes both.
Form the given diagram, the square consists of 10 rows and 10 columns which makes 100 (10×10) parts in it.
One fraction is obtained by dividing it by the total number of parts.
In this square, 21 shaded fractions are given.
∴ The fraction of shaded Area = 21/100.
Decimal of shaded Area=0.21.
(4 x a x a x a x a) x (4 x a x a x a x a)
