Answer:
<em><u>$79.38</u></em>
Step-by-step explanation:
Find the diagram of the question attached
Area of the parallelogram = Base * Height
Given
Base = 8.1m
Height = 3.5m
Area of the parallelogram = 8.1 * 3.5
Area of the parallelogram = 28.35m²
If the carpet is priced at $2.80 per square meter, then;
1m² = $2.80
28.35m² = x
x = 28.35 * 2.80
x = $79.38
<em><u>Hence the cost of the carpet is $79.38</u></em>

i hope this helpes
(f+g) (x) =0 for x=-2
f(x) = x^2 – 2x, g(x) = 6x + 4,
(f+g) (x) =f(x) +g(x) =
(x^2 – 2x) + (6x + 4) =
x^2 – 2x+ 6x + 4=
x^2 +4x+4
(f+g)(x) =x^2 +4x+4=0 (quvadratic equation)
x^2 +4x+4=x^2 +2x*2+2^2=(x+2)^2
then
(x+2)^2 =0
x+2=0
x=-2
