Solve each pair of simultaneous equations by substitution method
WARRIOR [948]

Answer:

x = 1       y = -4

Step-by-step explanation:

- Plug the value of y into the other equation.

x + 3y = -11

x + 3(-4x) = -11

x - 12x = -11

-11x = -11

x = 1

- Now substitute the value of x into any equation.

y = -4x

y = -4(1)

y = -4

Find the area of polygon​
Mumz [18]

Answer:

87 cm²

Step-by-step explanation:

there is 1 triangle and 1 rectangle in the diagram. so you have to find the area of the both polygons and sum up to find the total area of polygon

area of triangle formula:

\frac{1}{2}  \times base \times height

1) area of triangle AED

base = 12 cm

height = 4.5 cm

area:

\frac{1}{2}  \times 12 \times 4.5 = 27 {cm}^{2}

area of rectangle formula:

length \times height

2) area of rectangle ABCD

length = 12cm

height = 5 cm

area:

12 \times 5 = 60 \: cm {}^{2}

3) area of whole polygon

= area of triangle AED + area of rectangle ABCD

= 27 cm² + 60 cm²

= 87 cm²
