It looks like selections A and C are identical. (Neither is equivalent to 9^x.)
If B is supposed to be 3^(2x), it is equivalent to F and D and to the given expression.
Of course, D evaluates to 9^x, so is equivalent.
Choice E evaluates to 3^(x+2), which is not equivalent to 3^(2x).
The applicable choices appear to be
... B. 3^(2x)
... D. (3*3)^x
... F. (3^x)*(3^x)
Answer:
Width = x² + 5x - 4
Step-by-step explanation:
By the definition of an area model,
Area = Width × greatest common factor
Since, Area = 4x² + 20x - 16
And greatest common factor = 4
4x² + 20x - 16 = 4(Width)
By dividing both the sides of the equation by 4,
x² + 5x - 4 = Width
Therefore, width = (x² + 5x - 4) will be he answer.
<span> The statement given above of the Pythagorean Theorem correctly read as
</span><span>The sum of the squares of any two legs of a right triangle is equal to the square of the hypotenuse
</span>because as we know that Pythagorean theorem is expressed like that<span><span><span>a2</span>+<span>b2</span>=<span>c2
so option D is correct
hope it helps</span></span></span>
Answer:
The missing side, a = 100.50
Step-by-step explanation:
The given information are;
A = 18
B = 28
C = 100
a = Required,
The number of data points in the definition = 3, therefore, the figure is a three sided figure or a triangle
The sum of the given data is 18 + 28 + 100 = 146 which is less than the sum of the interior angles of a polygon, the minimum of which is 180° for a triangle.
However, the length of the two sides A and B are less than the third side C, therefore, the sides need more length for them to form a triangle
The fourth required information can be taken as the fourth side of a trapezium, to give;
Length of a = √((28 - 18)² + 100²) = 100.499, which can be written to the nearest 10th as 100.50.
