Answer:

x = -1 and y = 6

Step-by-step explanation:

using x = -b/2a

x = -4 / 2(2)

x = -1

y = 2(-1)² + 4(-1) + 8

y = 2 - 4 + 8

y = 10 - 4

Solve for x.<br> Greatly appreciate all efforts :)
Lelu [443]

Answer:

x = 11

Step-by-step explanation:

ΔLKM is an equilateral because a triangle with all 3 sides that are congruent is an equilateral triangle.

Angles in an equilateral triangle are all 60°.

Thus, ∠L = 60°.

=> 3x + 27 = 60

=> 3x = 33

=> x = 11

How do u answer thiss
nekit [7.7K]

Answer:

<em>15 times and more. After she pours the 15th container, in the middle of the next one, the work will be done.</em>

Step-by-step explanation:

<u>Length, Area, and Volume Scale Factors</u>

If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is a^2:b^2 and the scale factor of their volumes is a^3:b^3.

We are given the scale factor of the surface areas of two similar containers A and B as 4:25.

The length scale factor is

\sqrt{4}:\sqrt{25}=2:5

The volume scale factor is: 5^3:2^3 = 125:8 = 15.625

Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.

Thus, after she pours the 15th container, in the middle of the next one, the work will be done
