amid [387]

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!

A scale drawing is a reduced form in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension using the scale factor.

Scale factor = original dimensions / dimensions of the scale drawing

90 / 6 = 15

1 : 15

<h3>✽ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ✽</h3>

➷ 40 = 1.8c + 32

Subtract 32 from both sides:

8 = 1.8c

Divide both sides by 1.8:

c = 4.4
