Answer:

Step-by-step explanation:

5:4:3 = x:y:2

4:3 = y:2 Cross multiply

3y = 8 Divide by 3

y = 8/3 = 2.66'

5/x = 3/2

3x = 10 Divide by 3

x = 10/3

x = 3.33

Length of the wood = 2.66 + 3.33 + 2

Length of the wood = 8 feet

Does anyone know how to do this

Scilla [17]

Answer:

$7 {x}^{2} + 28x - 35 = 0$

$7 {x}^{2} + 35x - 7x - 35 = 0$

$7x(x + 5) - 7(x + 5) = 0$

$(x + 5)(7x - 7) = 0$

$(x + 5)(x - 1) = 0$

Guys please help me am I right

Elodia [21]

Answer:

$y \leqslant 6$

Step-by-step explanation:

The range is set of all y-values. The range starts from minimum value to maximum value.

We don't have minimum value (approaching negative infinity.)

We have maximum value at x ≈ 2 equal 6.

Therefore the answer is

-inf <= y <= 6. But we don't usually write that. Instead, we cut out -inf and we get —

$y \leqslant 6$
