Answer:

x = 8

Explanation:

$\frac{3x^2}{4} =48$

multiply both sides by 4: $3x^2=192$

divide both sides by 3: $x^2=64$

take the square root:

$\sqrt{x^2} = \sqrt{64} \\x=8$

3x^2 / 4 = 48

Multiply both sides by 4 to get rid of the four on the left.

3x^2 = 192

Divide both sides by 3

x^2 = 64

The square root 64 to get x

Remember there are two answers

x = 8 and x = -8

Show me how to graph f(x)=3/2 x + 2

Alexxx [7]

y = (3x)/2 + 2

Slope = 3/2

y-intercept = 2

The first point is y-intercept when x = 0 = (0,2). Now according to our slope we move 3 up (Why up? Because it's positive) and 2 right (Why right? Because it's positive).

When you move 3 up from (0,2), you get (0,5) and move 2 right which is (2,5).

Remember: slope = change in y / change in x

Points: (0,2) and (2,5)

In un trapezio rettangolo la base minore, il lato obliquo e l'altezza misurano rispettivamente 60 cm. 95 cm è 76 cm. Calcola il

Answer:

$2p=348 cm\: S=6726 cm^{2}$

Step-by-step explanation:

Ciao, come stai?

1) Per prima cosa, dobbiamo trovare la misura della base più grande. Scomponendo la figura possiamo visualizzare un triangolo e un quadrato. Ci sono somiglianze con gli angoli. Quindi è un triangolo rettangolo. Applichiamo il teorema di Pitagora:

$a^2=b^2+c^2\\95^2=b^2+76^2\\57=b$
