I need help please! ​
Sophie [7]

Answer/Step-by-step explanation:

Area of trapezium = ½*(AD + BC)*AB

Area = 42 cm²

AD = (x + 8) cm

BC = (x + 5) cm

AB = x cm

Plug in the values into the equation

42 = ½((x + 8) + (x + 5))*x

42 = ½((x + 8 + x + 5)*x

42 = ½(2x + 13)*x

Multiply both sides by 2

42*2 = (2x + 13)*x

84 = 2x² + 13x

2x² + 13x = 84

Subtract both sides by 84

2x² + 13x - 84 = 0

Use pi=3<br> Calculate the area of a circle with a diameter of 10cm
GalinKa [24]
Area of a circle is 75 cm².

Area of a circle is computed by multiplying pi to the square of the radius.

A = πr²

diameter = 10 cm
radius = d/2 = 10/2 = 5 cm
pi = 3

A = 3(5cm²)
A = 3(25cm²)
A = 75 cm²

F(x) = x2 + 1 g(x) = 5 – x<br><br> (f + g)(x) =
Gnom [1K]

Answer:

(f + g)(x) =  {x}^{2} - x + 6

Step-by-step explanation:

We have

f(x) =  {x}^{2}  + 1

and

g(x) = 5 - x

We want to find (f+g)(x).

By the algebraic properties of polynomial functions,

(f + g)(x) = f(x) + g(x)

(f + g)(x) =  {x}^{2}  + 1 + 5 - x

This simplifies to

(f + g)(x) =  {x}^{2}  - x + 6

We can't simplify further, hence the simplest form
