Answer:

Area of Square having side length equal to 7cm

    =(7)²

  =49 cm²

because ,Area of square=Side × Side

⇒Area of Circle having diameter 7 cm will be

      \text{radius}=\frac{\text{Diameter}}{2}\\\\\text{Area of circle}=\pi \times r^2\\\\=\frac{22}{7}\times (\frac{7}{2})^2\\\\=\frac{22\times 49}{7\times 4}\\\\=\frac{77}{2}\\\\=38.5 \text{cm}^2

  Area of square is larger than Area of circle by

    =49-38.5

   =10.5 cm²

Answer:  The area of the circle will be eleven-fourteenth of the area of square.


Step-by-step explanation:  Given that a square has a side of length 7 cm and a circle has a diameter of 7 cm. We need to find the statement which is true about the areas of these two figures.

The area of the square will be

S_a=7^2=49~\textup{cm}^2.

And, the area of the circle will be

C_a=\pi r^2=\pi \times \left(\dfrac{7}{2}\right)^2=\dfrac{\pi}{4}\times 49=\dfrac{22}{7\times 4}\times 49\\\\\Rightarrow C_a=\dfrac{11}{14}\times S_a.

Thus, the area of the circle will be eleven-fourteenth of the areq of the square.

Given the function f(x) = -5|x + 1| + 3, for what values of x is f(x) = -12? O X= -2. x = 1 O x= -2 x = 4 O x = 2. x = 4 O x = 2
puteri [66]

The values are x= -2 and x =4 of the given function f (x) =-5|x+1| +3

<h3>What is function?</h3>

Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

According to the question,

The given function is

f(x) = -5|x + 1| + 3

Here f(x) = -12

Substitute f(x) and solve for x

- 12 = -5|x + 1| + 3

By subtracting 3 on both sides

- 12 - 3 = -5|x + 1| + 3 - 3

- 15 = -5|x + 1|

By dividing -5 on both sides

3 = |x + 1|

We get absolute values for the function.

x + 1 = 3 , x + 1 = -3

By subtracting 1 on both sides

x + 1 - 1 = 3 - 1 = 2\\\\x + 1 - 1 = - 3 - 1 = -4\\\\x = 2 ,  x = - 4

Therefore, the values of x are 2 and - 4 of the given function f (x) =-5|x+1| +3
