Given

[tex]Expression = 40\% * 75[/tex]

[tex]Priya = \frac{2}{5} * 75[/tex]

Required

Is Priya correct?

We start by simplifying the expression.

[tex]Expression = 40\% * 75[/tex]

Express 40% as fraction

[tex]Expression = \frac{40}{100} * 75[/tex]

Simplify fraction: Divide numerator and denominator by 20

[tex]Expression = \frac{40/20}{100/20} * 75[/tex]

[tex]Expression = \frac{2}{5} * 75[/tex]

By comparing:

[tex]Expression = \frac{2}{5} * 75[/tex]

and

[tex]Priya = \frac{2}{5} * 75[/tex]

We can conclude that Priya is correct because:

[tex]40\% = \frac{2}{5}[/tex]

Answer:

X=0

Step-by-step explanation:

[tex]8(1 \times 5x) + 5 = 13 + 5x \\ 8 + 40x + 5 = 13 + 5x \\ 40x + 13 = 13 + 5x \\ 40x - 5x = 13 - 13 \\ 35x = 0 \\ x = 35 \times 0 \\ x = 0[/tex]

The solution to the equation is x = 0.

Here, we have,

Let's solve the equation step by step:

Distribute the 8 to the terms inside the parentheses:

8 + 40x + 5 = 13 + 5x

Combine like terms on both sides of the equation:

40x + 13 = 5x + 13

Subtract 5x from both sides to isolate the variable terms on one side:

40x - 5x + 13 = 5x - 5x + 13

Simplifying:

35x + 13 = 13

Subtract 13 from both sides to isolate the variable term:

35x + 13 - 13 = 13 - 13

Simplifying:

35x = 0

Divide both sides of the equation by 35 to solve for x:

35x/35 = 0/35

Simplifying:

x = 0

Therefore, the solution to the equation is x = 0.

[tex]10\ \text{sq. units}[/tex]

Step-by-step explanation:

The parabola's are

[tex]y=-x^2+9[/tex]

[tex]y=2x^2-3[/tex]

So

[tex]-x^2+9=2x^2-3\\\Rightarrow 12=3x^2\\\Rightarrow \\\Rightarrow x=\sqrt{\dfrac{12}{3}}\\\Rightarrow x=\pm 2[/tex]

[tex]y=-x^2+9=-(2)^2+9\\\Rightarrow y=5[/tex]

[tex]y=-(-2)^2+9=5[/tex]

So, the points at which the parabola's intersect each other is [tex](2,5)[/tex] and [tex](-2,5)[/tex]

The three points of the triangle are [tex](2,5)[/tex], [tex](-2,5)[/tex] and [tex](0,0)[/tex]

Area of a triangle is given by

[tex]A=\dfrac{1}{2}[x_1(y_2-y_3) + x_2(y_3-y_1) + x_3(y_1-y_2)]\\\Rightarrow A=\dfrac{1}{2}[2(5-0)+(-2)(0-5)+0(5-5)]\\\Rightarrow A=10\ \text{sq. units}[/tex]

Area of the triangle formed is [tex]10\ \text{sq. units}[/tex].
