Answer:

The equation that Howard can use to determine x is $x=15*6.2$

The height of the statue of liberty is $93\ m$

Step-by-step explanation:

Let

x-----> the height in meters of the statue of liberty

we know that

Using proportion

$\frac{1}{6.2}\frac{in}{m} =\frac{15}{x}\frac{in}{m}$

$x=15*6.2$ -----> equation that Howard can use to determine x

Answer:

x = 4, 7

Step-by-step explanation:

We start off with the equation $x^{2} -11x = -28$ . from there, we can add 28 to both sides to get $x^{2} -11x+28 = 0$ . From there, we have to factor the equation. In order to factor it, we have to ask ourselves what 2 numbers would add up to -11 and multiply to 28? In this case, the answer would be -7 and -4. So, we get the equation (x-7)(x-4) = 0. Then, we set each part of the equation = 0 to get the anwsers x = 4 and 7. Hope this helps!
