Which number line shows the solution to the quality -3x -5 <-2

1 answer:

3 0

No number line is shown. To solve the inequality, add 5 to get -3x < 3, and multiply by -1 (and remember to flip the sign!) to get 3x > 3. Divide by 3 to get x > 1.

Find the lateral area of the pyramid to the nearest whole number.

son4ous [18]

Answer:

The correct answer is first option. 204 m²

Step-by-step explanation:

Formula:-

Lateral surface area of square pyramid = 4 * area of triangle

To find the slant height of triangle(l)

l = √(6² + 6²) = 6√2

To find the area of triangle

Area = bh/2

b = 12 m

h = 6√2

Area = (12 * 6√2)/2 = 36√2

To find the lateral surface area of Prism

Lateral surface area of square pyramid = 4 * area of triangle

= 36√2 * 4 = 203.64 ≈ 204 m²

First answer is the correct option
