katovenus [111]

We are given dimensions of rectangular bedroom = length of 5m and width 3 m.

Also scale drawing of factor 1/50 of the original dimension.

In order to find the dimensions of scale drawing, we need to multiply scale factor by each dimension.

Therefore, length of the scale drawing is 5 * 1/50 = 1/10 m and

Let us convert it in centimeter now.

1 m = 100 cm

1/10 m = 100 * 1/10 = 10cm.

Width of the scale drawing = 3 * 1/50 = 3/50 m.

100*3/50 = 6 cm.

Therefore, the dimensions of a scale drawing of Elenas bedroom is length 10cm and width 6cm.

son4ous [18]

Answer:

g(-1) = 4

Step-by-step explanation:

Given:

g(x) = \frac{3x^2 - 2x + 7}{2x + 5}

To find g(-1), substitute x = -1

Thus:

g(-1) = \frac{3(-1)^2 - 2(-1) + 7}{2(-1) + 5}

g(-1) = \frac{3 + 2 + 7}{-2 + 5}

= \frac{3 + 2 + 7}{-2 + 5}

= \frac{12}{3}

g(-1) = 4
