The school is planning to add 2 new playgrounds. Each playground will be in the shape of a square that measures 10m by 10 m. Wha
mojhsa [17]

Answer:

Each playground will be 100 m2. Both playgrounds are 200 m2.

Step-by-step explanation:

Area of square is defined by a × a.  

a = length of side. In this case a is 10 m

So,  Area = 10 m × 10m

Area = 100 m2 (square meters). This is the area of one playground.

Two playgrounds will be the double, 200 m2

Write the equation of a line that passes through the points (-2, -8) and (2, -6).
Anna [14]

Answer:

y = \frac{1}{2} x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 2, - 8) and (x₂, y₂ ) = (2, - 6)

m = \frac{-6+8}{2+2} = \frac{2}{4} = \frac{1}{2} , thus

y = \frac{1}{2} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, - 6), then

- 6 = 1 + c ⇒ c = - 6 - 1 = - 7

y = \frac{1}{2} x - 7 ← equation of line
